Lamprologus ornatipinnis

Lamprologus ornatipinnis: a Lake Tanganyika cichlid for hard water

Lamprologus ornatipinnis is a cichlid from Lake Tanganyika, the long rift-valley lake of East Africa, and it belongs in a Tanganyikan aquarium rather than alongside the better-known Malawi cichlids. Each purchase is one live fish, sent at 3.5–4 cm. The most important thing to know before ordering is that it needs hard, alkaline, very clean water, held steady in an aquarium that has already matured. If your tank is set up for soft or acidic water, it is not the right home for this fish.

Name and identity

The World Register of Marine Species lists Lamprologus ornatipinnis Poll, 1949 as an accepted species in the cichlid family, Cichlidae. You may also see it labelled Lamprologus ornatipinis, with a single "n" in the second word. Both labels are used for this same fish; ornatipinnis is the accepted spelling and the one used throughout this guide. It is normally sold under its scientific name, so that is the name to search for and to quote when you ask about it.

What you receive

• One live Lamprologus ornatipinnis per purchase. Add more to your basket if you want more than one fish.
• Size at dispatch: 3.5–4 cm. That is the length of the fish when it is packed, not a forecast of how large it will grow.
• A fish hand-bagged in oxygen and packed by our own team, with our Live Arrival Guarantee behind it.

Sex is guaranteed only when the selected option explicitly states male or female. This Lamprologus ornatipinis listing has no sex-guaranteed option.

Is it the right fish for you?

A Lake Tanganyika fish

Lake Tanganyika is one of Africa's famous cichlid lakes, alongside Lake Malawi and Lake Victoria. OATA names julies (Julidochromis species), fairy cichlids (Neolamprologus pulcher), Tropheus and frontosa (Cyphotilapia) among the most popular Tanganyikan cichlids in the aquarium trade, and African lake cichlids as a whole range from shell-dwelling species that grow to about 6 cm to frontosa at over 30 cm. Choosing Lamprologus ornatipinnis means planning the tank around Tanganyikan water and Tanganyikan companions from the start.

Before you order

• The aquarium has been running long enough for ammonia and nitrite both to read zero.
• Your tap water has been tested for pH, general hardness and carbonate hardness, and sits close to the targets in the care tab.
• The filter is oversized for the tank, with aeration alongside it, and a heater holds 23–27°C.
• Any companions, present or planned, come from Lake Tanganyika.
• Someone will be at home on delivery day to receive the parcel and open it the same day.

The care advice on this page follows the Ornamental Aquatic Trade Association's guidance for African lake cichlids as a group, together with the RSPCA's general advice on aquarium filtration. Those figures set out the water, tank and routine that Tanganyikan cichlids need; the care tab explains how to reach them and, just as important, how to hold them steady.

Setting up the aquarium

Mature the tank before the fish arrives

A newly bought cichlid depends on a filter that is ready for it. Fish release ammonia into the water, and ammonia is toxic. In a working biological filter, beneficial bacteria convert that ammonia to nitrite, which is also toxic, and then to nitrate, which is safer. The RSPCA's aquarium welfare advice is blunt about it: no fish should be kept in a tank without a well set-up and maintained filter.

Those bacteria take time to build up, so set up, heat and run the aquarium well before you order, and check that ammonia and nitrite both read zero before the fish goes in. If this will be your first aquarium, our guide to preparing and maturing a first tropical tank takes you through the process step by step.

Stocking too quickly causes what OATA calls new tank syndrome. There are not enough nitrifying bacteria to deal with the extra waste, ammonia and nitrite rise to unhealthy levels, and fish may become ill or die. The bacterial population has to grow again every time more fish are added and feeding increases, so build up the numbers in stages rather than all at once.

How big an aquarium?

OATA's advice for African lake cichlids is to buy, within reason, an aquarium as large as possible. A larger volume keeps its temperature and water quality more stable, and stability is what these fish depend on. For a sense of scale, OATA's group sheet says a pair of the smallest shell-dwelling species needs an aquarium at least 45 cm long, while frontosa, which can grow to over 30 cm, needs one of about 180 cm and sometimes more as the fish set up territories.

Those two figures mark the ends of a very wide range; neither is a measurement for this fish. For Lamprologus ornatipinnis, size the aquarium for the whole community you plan to keep, for adult fish rather than the size that arrives in the bag, and for the filtration that community will need. OATA expresses its minimums as tank length, so compare aquariums by length as well as by litres, and choose the longer tank when you are torn between two.

Filtration and oxygen

OATA recommends an oversized filter for African lake cichlids, because some lake communities are deliberately kept a little crowded, and vigorous aeration so there is plenty of dissolved oxygen. In practice that means a filter rated for a bigger aquarium than yours, run alongside an air pump or other aeration. An oversized filter also gives you more margin when you add fish, feed a little heavily or miss a maintenance day.

Substrate and layout

OATA recommends a fine coral sand, or a similar substrate, for African lake cichlid aquariums; coral sand helps to buffer the water towards the hard, alkaline conditions these fish need. OATA also notes that rearranging the décor can reduce aggression, as fish find new territories. That is a good reason to build the layout from separate groups of rock and ornaments that you can move without stripping the whole tank, with more than one place for a fish to settle.

Heating

A reliable heater with its own thermostat, checked against a separate thermometer, keeps the aquarium within the 23–27°C range given in the water section. Read the thermometer when you feed, so a failing heater is caught within hours rather than days.

Water chemistry and testing

The numbers to aim for

The OATA care sheet for African lake cichlids describes these fish as specialised, needing particular water parameters. The values below are its guidance for the group, broad targets for lake cichlids generally rather than a species-specific optimum, and they are the range to keep Lamprologus ornatipinnis in.

Nitrate is measured against your own tap water, so test the tap as well as the tank. If your tap water already carries 10 mg per litre, the aquarium should stay at or below 30.

Before you order: test your water

Fill a clean container from the tap you will use for water changes, then test pH, general hardness and carbonate hardness. Enter the readings into our water matcher tool to see how they compare with the targets above. If the numbers are close, a coral sand substrate and regular water changes may be all you need to hold them. If your water is far softer or more acidic, you will be fighting it every week, and it is worth planning the tank around that before any fish arrives.

If the terms are unfamiliar, our guide to which aquarium water values to test and why explains what pH, GH and KH each describe and how they relate to one another.

When a reading is off

Holding the water steady

• Test at least once a week, so ammonia and nitrite cannot build up unnoticed between water changes.
• Treat all replacement water with a tap water conditioner to remove chlorine or chloramine before it goes into the aquarium.
• Keep a simple written log of each reading; a slow drift in pH or nitrate is far easier to spot on paper than from memory.
• Change one thing at a time. If a reading is off, correct it gradually over several water changes rather than with one large adjustment.

Weekly maintenance

OATA strongly recommends a partial water change of 25% at least once every week for African lake cichlids. Good husbandry matters here because these fish can be stressed by even small amounts of ammonia, so the routine below is part of keeping them, not an optional extra.

A weekly routine

1. Test ammonia, nitrite, nitrate and pH first, so you know how the tank stood before the change.
2. Siphon out about a quarter of the water, running the siphon over the substrate to lift solid waste.
3. Set aside a bucket of the water you have removed; it is the water to use for cleaning filter media.
4. Check the filter for blockages. If the media needs cleaning, rinse it lightly in that removed tank water.
5. Refill with tap water treated with conditioner, then check the heater and thermometer before you walk away.

Why filter media never goes under the tap

The beneficial bacteria that turn ammonia into safer nitrate live in the filter media. Chlorine or chloramine in tap water can kill that bacterial population, which is why OATA advises never running a filter under the tap. Rinsing it lightly in the tank water you have just removed cleans off the sludge while losing far fewer of the bacteria.

Keeping on top of it

A regular day each week works better than changing water whenever the tank looks dirty; a cichlid aquarium can look clear while nitrate is creeping upwards. If you go away, arrange for someone to test and change the water, or plan the break so the tank misses as little of its routine as possible.

Feeding

How much and how often

OATA's guidance for African lake cichlids is to feed only what the fish can eat within a few minutes, twice a day. Take care not to overfeed. Uneaten food breaks down and releases toxic waste into the water, and in a hard-water cichlid tank that shows up first as rising ammonia and nitrite.

A fish sent at 3.5–4 cm needs food it can take in comfortably, so choose small pellets or granules, or crumble larger ones. Watch the first few feeds closely: you want to see the fish take food with interest and the portion gone within those few minutes.

Choosing foods

Diets differ widely across African lake cichlids. OATA describes two ends of the range: herbivorous species such as Tropheus appreciate specialised cichlid foods with a high algae content, along with fresh vegetables, while some of the larger, more predatory species are carnivorous and need pellets with more animal content plus frozen foods such as brine shrimp, prawns or cockles.

For Lamprologus ornatipinnis, start with a good-quality cichlid food in a suitable size and build variety from there, noting what the fish accepts readily. If you are unsure what to offer, contact us with the foods you already have and we will help you choose.

Signs the feeding is right

• The fish comes forward for food and clears its portion quickly.
• Body shape stays well rounded without looking swollen.
• No food is left lying on the substrate after feeding.
• Ammonia and nitrite stay at zero on your weekly test.

OATA lists a change in body weight or condition, and a reduced intake or lack of interest in food, among the early warning signs of a problem, so a fish that stops feeding deserves a water test straight away.

Arrival and settling in

Your fish is hand-packed by our team: hand-bagged in pure oxygen and packed in an insulated poly box, with a heat pack when the weather calls for it. A licensed live-animal courier carries the parcel on a tracked service, and we email the tracking number and your confirmed delivery date so you know when to be in. Someone must be at the address to receive it, because live fish cannot be left unattended. The full terms are on our delivery and Live Arrival Guarantee page.

Opening the parcel

1. Before anything is opened, start one continuous video showing the sealed parcel with the outer box in view.
2. Keep that same recording running as you open the box, and show the fish still inside its sealed bag before anything is disturbed.
3. Float the sealed bag in the aquarium for 20–30 minutes before releasing the fish.
4. Release the fish into the tank, but never pour the bag water into your aquarium.

The parcel must be opened and inspected on the day it arrives. If anything has gone wrong, contact us the same day, with WhatsApp the fastest route, sending your order number and the unboxing video, and we will arrange a replacement or refund.

Introducing it to the aquarium

Check before delivery day that ammonia and nitrite are at zero and that the temperature sits inside 23–27°C. OATA suggests adding some African lake cichlids in groups, so that no single newcomer receives unnecessary aggression while it settles, and adding more peaceful species before more aggressive ones. When you are building a new Tanganyikan community, plan the order of introductions before the first fish arrives.

The first few weeks

The filter's bacteria have to catch up whenever fish are added and feeding increases, so test more often than weekly for the first couple of weeks after the fish goes in, and keep portions small. If ammonia or nitrite appear, follow the steps in the water section before adding anything else.

After release, watch rather than intervene, and give the fish time to explore and settle before you judge its behaviour.

Health checks and warning signs

What a healthy fish looks like

OATA describes healthy fish as having clear, bright eyes, undamaged fins, intact scales and no ulcers or bumps. Look for those signs when the fish arrives, and use them as your yardstick afterwards.

Changes to watch for

Every fish varies a little in behaviour and appearance, but changes in the following areas help you spot a problem before it becomes serious:

• Swimming: hanging at the surface, sitting on the bottom or swimming erratically.
• Colour: turning darker or paler than normal.
• Temperament: a change in aggression, or hiding more than usual.
• Breathing: gill covers moving slower or faster than normal.
• Appearance: white spots, fluffy growths, or loss of fins or scales.
• Condition: a gain or loss in body weight.
• Feeding: eating less or showing no interest in food.

What unsettles these cichlids

• Being kept alone: very few African lake cichlids do well singly.
• Ammonia or nitrite, even in small amounts.
• Water drifting away from the hard, alkaline targets in the water section.
• Persistent chasing by a tank mate.
• A crowded tank without the oversized filtration and aeration it needs.

What to do first

If you are worried about any fish, test the water quality before anything else, then contact us with the readings. Because these cichlids can be stressed by even small amounts of ammonia, the test results are the first thing to check. A daily look at every fish at feeding time is the simplest early-warning system you have.

Tank mates and grouping

Keep to Lake Tanganyika fish

OATA's general rule for African lake cichlids is to stock them only with other species from the same location, which for Lamprologus ornatipinnis means a Lake Tanganyika community. Mixing Malawi and Tanganyikan cichlids is not generally recommended because of their differences in temperament and behaviour. Our African cichlid range includes fish from more than one lake, so check where each species comes from before you plan it into a tank with this one.

Same lake is only the starting point

Sharing a lake does not make two cichlids good neighbours. African lake cichlids range from shell-dwelling species of about 6 cm to frontosa at over 30 cm, and their diets run from algae-grazing Tropheus to carnivorous predators. A Tanganyikan companion for Lamprologus ornatipinnis should also be close in size, similar in temperament and happy on the same foods, so that no fish is outgrown, bullied or outcompeted at feeding time.

How many to keep

Very few, if any, African lake cichlids do well when kept singly, and a fish kept alone is likely to become stressed. How many you should keep depends on the species, so plan for more than one fish and size the aquarium and filter to match. Each purchase is one fish and individual fish are not sexed, so if you are building a group, choose the number for the space you have rather than hoping for a particular mix.

Some lake cichlid species need slight overstocking, so that any aggression is spread out rather than falling on the weakest member of the group. That approach only works with the oversized filtration and weekly water changes described in the care tab.

Managing aggression

African lake cichlids vary in size and temperament, so research each species' compatibility before you add it. OATA's practical advice fits naturally into a stocking plan:

1. Choose the aquarium and filter for the finished community, not for the first fish.
2. Mature the filter until ammonia and nitrite both read zero.
3. Add the more peaceful species first.
4. Where a species does better in company, add its group together, so no single newcomer takes the brunt of any aggression.
5. Add the more aggressive species last, and test more often while the filter catches up with the extra fish.
6. If one fish is being singled out, rearrange the décor; the fish then have to find new territories.

Rule these out

• Lake Malawi cichlids, for the temperament and behaviour differences described above.
• Fish that need soft or acidic water, which cannot share a pH of 8.0–8.6 and hard water with this fish.
• Species kept outside 23–27°C, whether they need cooler or warmer water.

Questions to ask before adding a companion

• Does it come from Lake Tanganyika?
• Does it need the same hard, alkaline water and 23–27°C?
• Is its size and temperament a sensible match, bearing in mind that African lake cichlids vary widely in both?
• Will the tank still be large enough, and the filter still oversized, once it has been added?

Lamprologus ornatipinnis questions

What temperature, pH and hardness does Lamprologus ornatipinnis need?

Hard, alkaline, very clean water. OATA's broad guidance for African lake cichlids is 23–27°C, pH 8.0–8.6, general hardness 12–18°dH and carbonate hardness 10–15°dKH, with ammonia and nitrite at zero and nitrate no more than 20 mg per litre above your tap water.

What size aquarium does Lamprologus ornatipinnis need?

Buy as large an aquarium as you reasonably can, because a bigger volume keeps temperature and water quality more stable. OATA's group guidance puts even a pair of the smallest shell-dwelling African lake cichlids in a tank at least 45 cm long, so size yours for the whole Tanganyikan community you plan to keep.

How many should I keep together?

Plan for more than one. Very few, if any, African lake cichlids do well kept singly, and a lone fish is likely to become stressed. The right number depends on the species and your tank, so tell us the aquarium's length and current stock and we can help you plan.

Is Lamprologus ornatipinnis suitable for beginners?

It suits a keeper who already runs a mature, stable aquarium and is happy to test every week. African lake cichlids need particular water parameters and can be stressed by even small amounts of ammonia, so a brand-new tank is the wrong place to start.

What should I feed it?

Start with a good-quality cichlid food in pieces small enough to take comfortably, and add variety from there. Feed only what is eaten within a few minutes, twice a day, and avoid overfeeding, because uneaten food breaks down into toxic waste.

Is it aggressive?

Treat it as a cichlid that may defend its own space. African lake cichlids vary in temperament, so add more peaceful species first, bring newcomers in as a group where you can, and rearrange the décor if one fish keeps being chased.

Which fish can live with Lamprologus ornatipinnis?

Other Lake Tanganyika species that share its hard, alkaline water and suit its size and temperament. OATA advises stocking African lake cichlids only with species from the same lake, and mixing Malawi and Tanganyikan cichlids is not generally recommended.

How does Lamprologus ornatipinnis arrive alive in the UK?

It is hand-bagged in pure oxygen, packed in an insulated poly box with a heat pack when needed, and carried by a licensed live-animal courier. Someone must be in to receive it. Record one continuous unboxing video from the sealed parcel to the fish still in its bag, then float the bag for 20–30 minutes before releasing it.
