Red Fin Cichlid 4-7 cm (Tropheops tropheops)

Red Fin Cichlid 4-7 cm is the stocked size band for Tropheops tropheops, a territorial Lake Malawi mbuna best kept in a mature hard-water cichlid aquarium. The older trade name Pseudotropheus tropheops is still common in the hobby, but the important care points are the same: rocky territory, hard alkaline water and a vegetable-led diet.

Quick facts

Care notes

Plan this fish for a Lake Malawi rockscape rather than a soft-water community tank. Use stacked rock, caves and broken sight lines so each fish can claim space without holding the whole aquarium. Strong filtration, high oxygen and steady weekly maintenance matter more than chasing sudden parameter changes.

Red Fin Cichlids are active, assertive mbuna. They suit robust Malawi communities with other compatible mbuna and, in larger tanks, suitable Synodontis catfish. Avoid peaceful peacocks, delicate haps, small community fish and shrimp. For groups, one male with several females is safer than keeping two males in a cramped layout.

Feeding

Keep the diet vegetable-led. Spirulina flakes, algae wafers, herbivore cichlid pellets and occasional blanched greens fit the way this species grazes in nature. Avoid heavy meaty foods as a staple because mbuna are prone to digestive trouble when overfed rich protein.

Arrival support

Choose the 4-5 cm or 6-7 cm variant above, then acclimate slowly into a mature aquarium with the lights low. We pack live fish in insulated boxes with oxygenated bags and seasonal heat protection when needed, and orders are backed by our Live Arrival Guarantee with support from the Tropical Fish Co team.

Detailed Notes

Let me tell you about the red fin cichlid, Tropheops tropheops. If you’re looking for a lively Malawi cichlid with real character, this one’s a brilliant choice. It’s an active mbuna cichlid, full of energy, and it brings that classic Lake Malawi attitude to the tank. The red fin cichlid is colourful, hardy, and very much a fish with presence. And if you’ve been searching for aquarium livestock that suit a proper African cichlid setup, this is one that really stands out. Now, where does it come from?

This fish is endemic to Lake Malawi in East Africa, and that tells you a lot straight away. Lake Malawi is famous for its rocky shorelines and clear, mineral-rich water, and the red fin cichlid is right at home there. It prefers areas with rocky substrates, weaving through the stones and claiming little pockets of territory. In the wild, it grazes on aufwuchs, which is the algae and tiny associated organisms growing on those rocks. So when you picture this fish, think of sunlit rock faces, broken lines of stone, and a busy Malawi cichlid community all jostling for space.

That rocky habitat is a big part of why this fish behaves the way it does in the aquarium too. It’s a proper lake malawi mbuna, through and through. What I love about this fish is the colour. The red fin cichlid has vibrant red finnage, and that gives it a really eye-catching look in a tank full of rockwork. The body has that classic mbuna shape, built for darting in and out of caves and crevices. It reaches around fourteen centimetres in total length, so it’s not a tiny cichlid by any means.

It has enough size to hold its own, which suits its territorial nature. Males and females aren’t described here in detail, but the key thing to remember is the group structure. You’ll want one male with three or more females. That helps spread the attention around and keeps things calmer. In a busy Malawi setup, that’s often the difference between a tank that works and one that’s constantly on edge. For tank setup, this is where you want to think like a Lake Malawi aquarist.

The minimum tank size is two hundred and fifty litres, and honestly, that’s the starting point rather than the dream setup. These fish are territorial rock-dwellers, so abundant rock formations are essential. You want lots of broken lines of sight. Think stacked rocks, caves, gaps, and ledges. That gives each fish somewhere to claim and helps diffuse aggression. Overstocking is also recommended, which might sound odd at first, but with mbuna cichlids it can really help spread territorial behaviour around the tank instead of letting one fish bully another relentlessly.

A sandy or fine substrate works well with this style of setup, but the most important thing is the rockwork. Keep the layout open enough for swimming, but dense enough with stone to break up sightlines. The red fin cichlid is a middle-region fish, so it’ll spend a lot of time moving through the central areas and around the rocks. If you’ve ever watched an active african cichlid uk setup, you’ll know the tank is never still for long. That’s exactly the point. Water parameters are straightforward, but they matter.

Keep the temperature between twenty-four and twenty-eight degrees Celsius. Aim for a pH between seven point five and eight point five. Water hardness should sit between ten and twenty-five dGH. Those are classic Malawi conditions, and they suit this species well. The red fin cichlid is hardy and adaptable, but it still wants stable water. As with any Malawi cichlid, consistency is your friend. Regular maintenance and clean water will go a long way towards keeping them settled and healthy. This is a fish that appreciates the right environment more than fancy extras.

Feeding is another area where it pays to keep things simple and suitable. The red fin cichlid is a herbivore, so the diet should be based around spirulina flakes, algae wafers, cichlid pellets, and blanched vegetables. That’s the kind of food this fish is built for. It grazes naturally in the wild, so plant-based feeding makes sense in captivity too. One really important point here is to avoid high-protein foods. That’s not just a preference, it’s a health issue. High-protein feeding can lead to Malawi bloat, and nobody wants that.

So keep the menu herbivorous and steady. Small, regular feeds work well. You want enough variety to keep the fish interested, but not so much richness that you upset its digestion. If you’re used to feeding community fish, this is a slightly different mindset. Think algae, greens, and quality cichlid foods designed for mbuna. Behaviour-wise, this is an active fish with a strong territorial streak. You’ll notice them moving around the rockwork, patrolling their space, and generally keeping busy. They’re not the sort of fish that just hover in one corner all day.

There’s always a bit of energy to them. That aggression is part of the package, though, so it’s best to expect some pushing and posturing, especially in the wrong setup. In a well-planned tank, that behaviour becomes much more manageable. The fish can focus on their own territories rather than fighting over everything. If you’ve ever watched a proper Malawi cichlid tank, you’ll know there’s a constant rhythm to it. A bit of chasing, a bit of displaying, then back to grazing and cruising. That’s the red fin cichlid in a nutshell.

Compatibility needs careful thought. Good tank mates include other mbuna and Synodontis. That’s the safest direction to go in. Other mbuna tend to understand the same kind of territorial language, so they’re a more natural fit. Synodontis can also work well alongside Malawi cichlids, giving you some variety without upsetting the balance too much. But there are fish you should avoid. Peaceful Haps are not a good match, and neither are peacocks, small fish, or shrimp. The reason is simple. The red fin cichlid is territorial and aggressive, so peaceful species are likely to get stressed or bullied.

Small fish are at risk of being harassed, and shrimp would be too vulnerable. If you want a Malawi community, keep it focused on robust species that can cope with the pace. And if you’re building out a proper lake malawi mbuna tank, remember that rockwork and overstocking are part of the compatibility strategy too. It’s not just about who you add. It’s about how the whole tank is arranged. That’s why a thoughtful african cichlid uk setup matters so much. If you’re browsing aquarium livestock and comparing options, this is one where planning really pays off.

Here’s something really interesting about breeding. The red fin cichlid is a maternal mouthbrooder, and it breeds readily in captivity. That makes it a fairly easy breeder compared with many other fish. The breeding behaviour is part of what makes Malawi cichlids so engaging to keep. Once you understand the group structure and the territorial nature of the species, breeding becomes much more achievable. A single male with multiple females is the usual approach, and the fish will do the rest. You don’t need to overcomplicate it.

Just make sure the tank is well set up, the water is right, and the fish are settled. With the right conditions, this species can be very productive. It’s one of those fish that gives you a real glimpse into the natural behaviours of Lake Malawi. Health-wise, prevention is the big thing. Keep the water stable, feed the right diet, and avoid high-protein foods. That helps reduce the risk of Malawi bloat, which is one of the main concerns with herbivorous mbuna cichlids. Also, don’t underestimate the effect of stress.

Too little space, not enough rockwork, or poor tank mate choices can all lead to problems. A calm, well-structured environment does a lot of the heavy lifting here. The red fin cichlid is hardy, but like any fish, it does best when its needs are met from the start. What makes this fish such a good option is that it gives you all the energy and colour people want from a Malawi cichlid, without being overly delicate. It’s a proper mbuna cichlid with personality, and it suits aquarists who want something active and rewarding.
