Powder Blue Cichlid (Chindongo socolofi)

Recognise a rock-dwelling Lake Malawi cichlid

The Powder Blue Cichlid (Chindongo socolofi) is a Lake Malawi mbuna that reaches a recorded maximum of 6.7 cm standard length. Also known in the aquarium trade as Pindani, this territorial cichlid suits a keeper prepared to provide a rocky, hard-water Malawi aquarium with mature filtration and carefully screened companions. The older scientific name Pseudotropheus socolofi still appears in books and aquarium discussions, but both names refer to this powder-blue cichlid. It belongs in a planned Malawi aquarium rather than a peaceful general community.

Its colour is shared by males and females: Seriously Fish describes both sexes as displaying the bright powder-blue colour associated with the species. Colour alone must therefore never be used to decide sex. The darker fin edges, faint vertical markings and active cichlid profile shown in the gallery make it a distinctive fish, but the practical attraction is its constant movement between rockwork and nearby open areas.

FishBase describes its wild habitat as shallow freshwater at depths of 4–10 metres in Lake Malawi, mostly over sand, while territorial males remain close to rocks. It feeds from the biocover growing on rock and sand. Those behaviours explain the central aquarium decisions: provide sand, divide the aquarium with caves and rock piles, and make vegetable matter and algae-based food the foundation of feeding.

This mbuna suits a keeper prepared to manage territory as carefully as water quality. Rockwork must provide hiding places and interrupted sight lines, while open areas still allow swimming. The biological filter needs to be mature, water must remain hard and alkaline, and companions must be chosen for compatible water, diet, adult size and temperament.

Choose a dispatch size and plan for growth

One purchase supplies one animal in the size chosen from the live selector. The size labels are 4–5 cm, 6–7 cm, 7–9 cm and 9–10 cm. Use the selector for the live choices rather than relying on a static description. The size you select is the size supplied, not the adult size.

Sex is guaranteed only when the selected option explicitly states male or female. This Powder Blue Cichlid listing has no sex-guaranteed option. Plan group composition without assuming a particular sex ratio.

Some gallery images are representative, based on reference photographs of this species, and none shows the exact animal supplied, so colours can look slightly different from the live animal.

FishBase gives a maximum recorded length of 6.7 cm standard length for a male or unsexed fish, while the Seriously Fish aquarium profile uses 11.5 cm standard length as its planning reference. Allow for the larger planning figure when deciding whether the aquarium has enough floor area and territory; it is a planning reference rather than a promise that every individual will reach that measurement.

Seriously Fish specifies an aquarium base of 90 × 45 cm and a volume of about 154 litres. Treat both dimensions as part of the decision. A tall aquarium with a smaller base may hold a similar volume but offers less room for separate territories, caves and open swimming areas.

For routine aquarium care, use 24–26°C, pH 8.0–8.6 and general hardness of 12–18 dGH. FishBase places the fish at 24–26°C in nature, while Seriously Fish gives 24–28°C, pH 7.6–8.8 and 10–25 dGH for aquarium care. OATA’s Malawi-cichlid sheet gives group guidance: 23–27°C, pH 8.0–8.6 and 12–18 dGH. The routine targets below are the overlap of those applicable ranges.

Build caves with room to swim

Start with the aquarium footprint rather than the appearance of an individual dispatch-sized fish. A base of 90 × 45 cm and a volume around 154 litres provide the species planning point. If the aquarium is intended to hold a broader Malawi community, the community calculation is different: OATA recommends at least 200 litres for a reasonable-sized community.

Divide the layout into useful areas

Arrange several piles rather than one exposed shelter. Seriously Fish recommends lots of caves and hiding places while preserving open swimming areas. This gives a chased fish more than one route out of view and reduces the value of any single cave. Watch the completed layout from each end of the aquarium: if every space is visible in one uninterrupted line, add another visual break.

A sandy substrate is preferable. OATA notes that Malawi cichlids will often dig and rearrange substrate, so delicate planting should not be the foundation of the design. Hardy plants attached to décor are less exposed to uprooting, but the essential structure remains sand, rocks, caves and swimming room.

Coral sand or a similar substrate may help buffer the water where that approach suits the measured tap water. Test before relying on décor to produce the required chemistry. The target is stable pH and hardness within the stated range, not a particular visual style.

Check the layout before adding fish

• Confirm that several caves remain accessible.
• Make sure open water has not been filled entirely with rock.
• Look for more than one route between the main areas.
• Measure the aquarium base as well as its litre capacity.
• Leave the filter outlet and aeration able to move the surface strongly.

Hold hard, alkaline water steady

Set the aquarium to 24–26°C, pH 8.0–8.6 and 12–18 dGH. These routine values are the overlap of the applicable FishBase, Seriously Fish and OATA ranges. Measure the aquarium rather than assuming that hard-looking décor has produced hard, alkaline water.

Use the water chemistry guide to understand pH, general hardness, carbonate hardness, ammonia, nitrite and nitrate. Once you have actual test results, the water matcher can compare them with the care targets.

Check the source water as well as the aquarium. For example, a tank reading pH 7.8 sits below the routine target even if the water looks clear. A hardness reading of 8 dGH is also below the stated range. Resolve those differences before introducing the fish, then test regularly so a gradual change is found before behaviour or feeding is affected.

Temperature deserves the same discipline. A heater setting is not a water measurement, so confirm the result with a thermometer. Seriously Fish estimates roughly 175–250 W of heating for an aquarium around 154 litres when the room is around 20°C. The required heater arrangement therefore depends on the aquarium volume and room temperature, while the water itself must remain within 24–26°C.

Avoid chasing a single midpoint from day to day. A stable reading anywhere inside the routine range is more useful than repeated intervention that moves the aquarium back and forth. Record the result at the same point in the weekly routine so changes are easy to notice.

Mature filtration before adding fish

Use a properly established biological filter before the Powder Blue Cichlid enters the aquarium. The RSPCA explains why biological filtration is essential: fish waste releases toxic ammonia, beneficial bacteria convert it to nitrite, and another stage converts nitrite to the safer nitrate. Ammonia and nitrite must both read 0 mg/l before livestock is added.

If this is a new aquarium, follow the first tropical tank guide to prepare and mature it before arranging delivery. Clear water alone does not show that the biological filter can process fish waste; the zero readings are the decision point.

Size flow for the aquarium

Seriously Fish recommends turnover of four to five times the aquarium volume each hour. For a tank around 154 litres, its filter example is rated at approximately 615–770 litres per hour. The calculation is straightforward:

• Four times turnover: 154 × 4 is about 616 litres per hour.
• Five times turnover: 154 × 5 is 770 litres per hour.

Use that range when comparing the filter rating for an aquarium of this volume. If the aquarium is larger, apply the same four-to-five-times calculation to its actual litres rather than carrying over the 154-litre figure.

OATA recommends an oversized filter and strong aeration for crowded Malawi communities. Surface movement is therefore part of the design, not an optional visual effect. Check that the outlet and aeration create active movement without removing all calmer routes between the rocks.

Increase the biological load slowly

Additions increase waste and feeding, so the filter’s beneficial bacterial population must grow with the load. OATA warns that adding too many fish too quickly may cause new tank syndrome, with ammonia or nitrite rising because the bacteria cannot process the increased waste. Test after any stocking change and do not make another addition while either toxic reading is above zero.

Feed a vegetable-led mbuna diet

Build the diet around vegetable matter and algae-based food. In Lake Malawi, this fish feeds from biocover on rocks and sand. In the aquarium, Seriously Fish recommends that vegetable matter form a large proportion of the diet, with spirulina flakes, blanched spinach and nori among the stated choices.

Use a simple daily pattern

• Offer a specialised Malawi cichlid food with a high algae content.
• Include spirulina flakes or another quality algae-based dried food.
• Use blanched spinach or nori as vegetable variety.
• Supplement with suitable live or frozen foods rather than making them the staple.
• Never feed beefheart or other red meat because it interferes with this fish’s digestive system.

OATA advises feeding Malawi cichlids twice a day and giving only what they can eat within a few minutes. Start with a modest portion, watch the fish eat, and stop before food is left to break down. “A few minutes” is a limit, not a reason to keep adding food until the time has passed.

Use the same portion test at both feeds. If food remains after the fish lose interest, reduce the next portion. Uneaten food releases waste as it breaks down, increasing the demand on the filter and working against the ammonia, nitrite and nitrate targets.

Natural grazing behaviour does not replace planned feeding. Biocover on aquarium rock may encourage the fish to pick at surfaces, but the routine still needs a nutritionally suitable Malawi food with a high algae content. Equally, eagerness to take richer food does not make it the correct staple; vegetable matter should continue to form the large proportion.

Keep feeding decisions separate from aggression. A fish that repeatedly misses food because it is being driven away needs a territory and stocking review, not simply a larger amount scattered into the tank. More food increases waste without removing the cause of the exclusion.

Keep a weekly water-care routine

Carry out a 25% partial water change at least once every week. Use a siphon to remove solid waste from the substrate, and treat replacement tap water with conditioner before it enters the aquarium so chlorine or chloramine does not damage fish or filter bacteria.

Complete these checks each week

1. Measure ammonia and confirm 0 mg/l.
2. Measure nitrite and confirm 0 mg/l.
3. Compare nitrate with the normal tap-water reading.
4. Check temperature, pH and hardness against the routine targets.
5. Change 25% of the water; complete this at least once each week.
6. Check the filter for blockages and confirm strong surface movement.

OATA’s nitrate limit is no more than 20 mg/l above the normal tap-water level. This is a difference rather than a single universal reading. If the tap water contains 10 mg/l nitrate, the aquarium should not exceed 30 mg/l under that rule. If the tap-water result changes, recalculate the aquarium limit from the new baseline.

Do not wash biological filter media under the tap. Chlorine or chloramine may kill the beneficial bacteria established in it. When cleaning is needed, rinse the media lightly in water removed during the partial change. This preserves more of the bacterial population while clearing debris.

Keep the maintenance sequence consistent so omissions are obvious. Testing before the water change shows the conditions the fish experienced during the week; checking equipment during the same session catches a blocked filter or reduced aeration before another seven days pass.

Respond to any ammonia or nitrite reading immediately by stopping further livestock additions, checking filtration and carrying out the necessary water-quality response. Do not treat a zero reading from a previous week as permission to skip the next test, particularly after stocking or feeding has increased.

Introduce the fish without strengthening old territories

Prepare the aquarium before the journey. Confirm 0 mg/l ammonia and nitrite, check that temperature and mineral readings are within range, and make sure someone can receive the parcel so live fish are not left unattended. Read the current delivery, acclimatisation and Live Arrival Guarantee terms before the delivery window.

Follow the arrival sequence

1. Start filming before opening the parcel, keeping the sealed parcel and outer box visible.
2. Open the parcel in one continuous take and show the fish while it remains inside the sealed bag.
3. Float the bag in the aquarium for 20–30 minutes.
4. Transfer the fish without pouring transport water into the aquarium.
5. Watch where it settles and whether another fish immediately blocks access to shelter.

The aquarium must already be ready before the parcel arrives. Floating the bag covers the immediate acclimatisation step; it cannot mature a filter, correct unsuitable water or create missing territories.

For an established Malawi aquarium, rearranging some décor before introduction can reduce aggression as resident fish find new territories. OATA also recommends adding Malawi cichlids in groups rather than leaving one new individual to receive all settling aggression, and introducing more peaceful species before more aggressive ones. Apply those principles only within a stocking plan that the aquarium volume and filter can support.

Use the first day to assess access

Do not use extra feeding to distract from a poor introduction. Feed according to the twice-daily, few-minutes rule when the fish is participating, and remove the cause if it cannot reach food because of sustained aggression.

Act on changes in behaviour or condition

Learn the fish’s usual swimming, feeding and use of shelter. A change from that normal pattern is more useful than judging one isolated movement. OATA highlights changes in swimming, colour, temperament, breathing, appearance, body condition and feeding as signs that require attention.

A torn fin combined with repeated chasing points to a territory or compatibility problem that water treatment alone will not solve. Rearrange décor to interrupt established territories and assess whether the stocking plan gives the targeted fish a safe route to shelter.

If several fish change behaviour together, test the aquarium before assuming an individual health problem. Ammonia and nitrite must remain at zero, while temperature, pH and hardness should remain in their routine ranges. Check the filter for blockage and confirm that surface movement remains strong.

Do not begin an undiagnosed treatment from appearance alone. Test the water, note the exact changes and contact us for guidance when livestock health changes. Clear details about breathing, swimming, appetite, visible marks and recent water results make the next decision more useful.

Plan a Malawi group, not a shoal

The Powder Blue Cichlid is not a social shoaling fish. Group keeping is used to manage a territorial Malawi community, not to meet a need to swim in a tight group. OATA warns that small Malawi groups often fight and says they can be kept in groups of at least 15, with slight overcrowding used to spread aggression. That approach requires filtration, aeration, aquarium volume and maintenance capable of handling the resulting load.

Do not apply the 154-litre species planning figure to a 15-fish community without recalculating the whole aquarium. OATA recommends an aquarium of at least 200 litres for a reasonable-sized Malawi community, while advising an aquarium as large as practical. Adult dimensions, territory, waste production and the temperament of every proposed fish still need to fit.

Separate the main stocking decisions

Because the offer does not guarantee sex, do not build a plan that depends on receiving a particular ratio. Watch the group as individuals settle and be prepared to revise territories or stocking if one fish receives continuous pressure.

A large fish count is not a substitute for compatibility. Slight overcrowding is a specific Malawi aggression-management approach and must remain within reason. It only works alongside oversized filtration, strong aeration, weekly maintenance and a layout that provides multiple hiding places. If those conditions cannot be met, do not increase numbers simply to reach a group figure.

Screen every companion before mixing

Avoid a general community aquarium and avoid large or aggressive mbuna. Seriously Fish describes this species as not especially aggressive for a mbuna, but still unsuitable for a general community tank. A more aggressive cichlid can dominate it, while a peaceful community plan does not match its territorial behaviour or Malawi water requirements.

Potential companions named by Seriously Fish include Aulonocara, Copadichromis and quieter mbuna such as Labidochromis caeruleus. OATA also allows some Lake Malawi Synodontis species in Malawi-cichlid aquariums. These are screening candidates, not automatic matches.

Check five points before mixing

1. Water: every fish must suit the same hard, alkaline conditions.
2. Diet: feeding must not force this mbuna onto a rich animal-based staple.
3. Adult size: compare mature planning sizes rather than dispatch sizes.
4. Temperament: exclude large or aggressive mbuna and plans built around peaceful community fish.
5. Space: provide enough base area, caves and separate territories for the whole group.

Small Malawi groups require particular caution because aggression may concentrate on one individual. More than one male also needs a larger aquarium, with each male given several females where the sexes are known. Watch for one fish being kept away from food or shelter, not just for brief chasing.

Browse the African cichlid collection to compare identities and care needs, then assess the complete combination rather than choosing by colour. A named candidate may still be unsuitable when aquarium dimensions, existing territories or diet differ. Ask us with the aquarium dimensions, water readings and full livestock list for a stocking and compatibility assessment.

Answer key buying and care questions

How big does Chindongo socolofi get?

This fish reaches a recorded maximum of 6.7 cm standard length according to FishBase. Plan its territory around a 90 × 45 cm aquarium base rather than judging space by its dispatch size.

What size aquarium does the Powder Blue Cichlid need?

Use an aquarium with a 90 × 45 cm base and about 154 litres for the species planning point. OATA recommends at least 200 litres for a reasonable-sized Malawi community.

How many should I keep together?

This fish is not a shoaling species. OATA says Malawi cichlids can be kept in groups of at least 15 because small groups often fight, but that community approach needs at least 200 litres, oversized filtration, strong aeration and a complete stocking assessment.

Is the Powder Blue Cichlid suitable for beginners?

Seriously Fish recommends it as a beginner’s mbuna, but it still needs a mature rocky aquarium, hard alkaline water, managed territories and screened Malawi companions rather than a peaceful general community.

What does the Powder Blue Cichlid eat?

Feed twice daily and offer only what it can finish within a few minutes. Vegetable matter should form a large proportion of the diet, using algae-rich Malawi food, spirulina flakes, blanched spinach or nori, with live or frozen food as a supplement; never feed beefheart or other red meat.

What temperature and pH does it need?

Keep it at 24–26°C, pH 8.0–8.6 and 12–18 dGH. The temperature is the FishBase, Seriously Fish and OATA overlap, while the pH and hardness are the overlap of Seriously Fish and OATA; ammonia and nitrite must remain at 0 mg/l.

Is the Powder Blue Cichlid aggressive or likely to nip fins?

It is territorial and not especially aggressive for a mbuna, but it is unsuitable for a general community aquarium. Judge compatibility through territorial pressure, chasing, access to shelter and fin condition.

Which animals can live with it?

Avoid a general community aquarium and large or aggressive mbuna. Carefully screened candidates include Aulonocara, Copadichromis, quieter mbuna such as Labidochromis caeruleus, and some Lake Malawi Synodontis, provided water, diet, adult size, temperament and space all align.

How does the fish arrive alive in the UK?

Someone must be present to receive it. Film every delivery continuously from the sealed parcel as it is opened, showing the fish still inside the sealed bag; float the bag for 20–30 minutes, then transfer the fish and never pour the bag water into the aquarium.
