A Simple African Cichlid Care Guide (5 Things You Must Know)

African cichlids are easy to keep alive and hard to keep well. Give them hard, alkaline water, a big tank, a lot of filtration, and more fish than feels right, and they’ll color up like nothing else in freshwater. Get one of those wrong, and you’ll see faded fish, torn fins, and a tank boss picking off everyone else.

I’ve kept African cichlids for 11+ years, including a 75-gallon, a 210-gallon, and now they’re in a 450-gallon overstocked show tank that runs on a custom sump while doing 80% water changes every single week. Everything below is what I actually do, with the numbers. No fluff.

African Cichlid care at a glance

Tank size and setup

Start at 55 gallons and go bigger if you can. Length matters more than height: cichlids claim territory along the bottom, and a long tank gives the losers somewhere to go.

My current setup is a 450G, 8 feet long x 3 feet wide x 28 inches tall. I’m using a Custom Aquariums Seamless sump for filtration, which beats 3 or 4 canisters that would be needed on this tank. I’m currently growing out about 50 baby Frontosa African Cichlids that will eventually be added to this tank!

Substrate

Use sand, crushed coral, or aragonite. Crushed coral and aragonite slowly release minerals that help hold your pH and hardness up, which is exactly what these fish want. One trick I like: hide a bag of crushed coral behind a 3D background or in your sump. You get the buffering without having it all over the bottom of the tank.

Rockwork

Build caves and break lines of sight, but leave open swimming space in front. You want enough hiding spots that a chased fish can disappear, and enough open water that the tank doesn’t feel like a maze. Stack rock directly on the glass or bottom before adding sand, so digging fish can’t undermine it.

Flow

African cichlids are fine with current as long as they have somewhere calm to rest. I run wavemakers 24/7 and only switch them off during feeding. On my 450, I use 3 Ecotech MP40s, and they keep waste moving toward the filters instead of settling in the rockwork.

Lighting

I run 4 AI Blade Freshwater lights, which have amazing intensity and color. These are not cheap lights, but once you see them, you understand why.

Water parameters (and how I hit them)

African cichlids want hard, alkaline water: pH 7.8–8.5 and a steady 78–84°F. I keep mine at 80°F. Stability matters more than any single number, so don’t let pH swing more than about 0.3 in a day.

My tap water: Comes out very close to neutral, 7.0, but I manipulate the PH with salts and buffers to raise it to about 8.0-8.2ph

Here’s what I add with every water change:

1. Seachem Malawi/Victoria Buffer to raise KH and hold pH.
2. Seachem Cichlid Lake Salt for the hardness and minerals these fish come from. (GH)
3. Seachem Cichlid Trace, which I use religiously because water changes and fish both use up trace elements.

Mix the buffer and salt into a bucket of new water first, not straight into the tank, so you’re not dumping a pH spike on your fish. Crushed coral or aragonite in the substrate (or hidden behind the background) keeps things from drifting between changes.

Test pH, ammonia, nitrite, and nitrate. Ammonia and nitrite should always read 0. Nitrate tells you when it’s time for a water change, which is the next section.

Filtration and water changes

An overstocked cichlid tank lives or dies by these two things.

Filtration

The usual advice is to turn your tank volume over 4–6 times an hour. For African Cichlids, I aim for 8–10. On my 210 I ran two Fluval FX6s; on my 75, an FX6 and a Fluval 407. On my 450, a huge sump!

For bio media, I currently use Seachem Matrix, but with bigger tanks with bigger bio-loads needing more bio-media, I know that can get expensive. I once did an experiment where I pulled all the expensive stuff out of both FX6s and replaced it with plain kitchen pot scrubbers. Ammonia and nitrite stayed at 0. Here’s the full experiment.

With two filters, I clean them on alternating schedules so I never wipe out all my beneficial bacteria at once.

Water changes

I do 80% water changes every week on an overstocked tank. That sounds extreme until you test: my nitrates climbed to 40–80 ppm in about a week. My rule is simple. When nitrates hit about 40 ppm, change the water. A lightly stocked tank might only need that every 2–4 weeks; your test kit tells you, not the calendar.

How I do it:

1. Drain with a Python (or a pump) and vacuum the sand as you go.
2. Dose dechlorinator for the full tank volume, not just the new water. Seachem Prime or Safe both work.
3. Refill with temperature-matched water, mixing in buffer, Lake Salt, and Cichlid Trace.

I’ve been using the Vivosun 2700GPH pump to drain my big tanks for a few years now, and it still works like a beast!

Feeding: my exact recipe

Most cichlid pellets are fine as a base, but processing strips out nutrients. So I add them back. Here’s what I fed about 30 fish:

Mix it all and let the pellets soak for 20–30 minutes before feeding. They should finish everything in about a minute. If food is hitting the sand, you’re feeding too much.

Once a week, they get frozen krill as a treat. You can find all of these foods and supplements in my affiliate shop.

One caution: many Mbuna are mostly plant and algae eaters. Lean their diet toward veggie formulas and go light on the high-protein stuff; too much protein is a common trigger for bloat.

I feed my adult-sized African Cichlids only once per day, and I fast them on Sundays.

Stocking and aggression: why I overstock

Overstocking is the number one way I control cichlid aggression. With only a few fish, the dominant male picks one target and hammers it until it dies. With a crowd, nobody can hold a territory for long and the aggression gets spread thin.

The catch: overstocking only works if you pay for it with the filtration and 80% weekly water changes above. Skip those and you just have a crowded, toxic tank.

Rough numbers for a 55 gallon:

Mbuna are more aggressive than Peacocks and Haps, which is why you need more of them to spread it out. I’ve kept 25 adult-sized Peas & Haps in a 75 gallon tank with no problems because I was over-filtering,

Adding new fish

Add 3–5 fish at a time, never one. A single new fish becomes everyone’s target. Rearranging the rockwork on the same day helps too, because everyone has to re-stake their claim.

When one fish becomes a bully

Pull it into a separate tank for about 2 weeks. That’s usually long enough for it to lose its place in the pecking order, and it comes back to a tank that has moved on without it. In my experience, this works about half the time. If it doesn’t, rehome the fish.

Tank mates, males vs females, and breeding

Tank mates

Keep it simple. In my 210, the only non-cichlids were a single Bristlenose Pleco, which handled algae without growing into a monster like a Common Pleco, and a handful of Clown Loaches. They both do great with African Cichlids. I have also always kept Gordo, my 1 and only Blood Parrot Cichlid, with my Africans since the beginning of my journey. While that’s not very common and sometimes doesn’t work, Gordo is the OG and handles his own!

What doesn’t work: soft-water fish. Angelfish, Discus, and Oscars get beaten up fast and want completely different water. I break those down here: African cichlids with Angelfish and with Oscars.

All-male vs mixed

For a beginner, I recommend an all-male tank. The males stay colored up because they’re always competing, there are no fry to deal with, and no female gets chased to death.

If you keep males and females together, never do one female per male. She’ll be chased nonstop, and the males will want to kill each other for her. Aim for 4–5 females for every male so they can take turns resting.

Telling them apart

Color and egg spots are clues, not proof. The only reliable way is venting (checking the vent under the fish), and it works best once fish are around 3–4 inches and about a year old. How to vent African cichlids.

Breeding

Most African cichlids are mouthbrooders: the female carries eggs and fry in her mouth for weeks. If you want to breed them seriously, give a male and his 4–5 females their own tank. I don’t breed because I just don’t have the time, space, and patience. But I have had a batch of fry born in my FishKave that I’m currently growing out.

Common problems and how to fix them

Mistakes I see (and made)

• Adding one fish at a time. Add 3–5.
• Keeping one female with a male. Go 4–5 females per male, or all male.
• Buying the prettiest fish without checking how big it gets or how mean it is.
• Mixing Africans with soft-water fish like Angelfish or Oscars.
• Overstocking without upping filtration and water changes to match.
• I personally made a huge mistake of NOT applying proper quarantine techniques and wiped out my entire tank due to disease.

FAQ
