Edward cichlid

Where they come from

Edward cichlids (Haplochromis pharyngalis) are Victorian haps from Lake Victoria and nearby waters. They come from big, open lakes where the water is hard and alkaline, and the fish are constantly sorting out who is boss. That background explains a lot of their attitude in a glass box.

Setting up their tank

I would not keep this fish in a small tank. They are active swimmers and the males in particular want room to posture and patrol. A 4 foot tank is where they start acting like themselves, and 5-6 feet makes everything easier if you want a community of haps.

• Tank size: 75 gallons/4 foot minimum for a small group, bigger if you are mixing haps
• Temperature: 76-80F
• pH: 7.8-8.6
• Hardness: moderate to hard (they look best and act calmer in harder water)
• Filtration: strong, with lots of bio media and decent flow

Decor-wise, I go for a mix of open swimming space and rock piles that break line of sight. You are not trying to build a reef of rocks like mbuna tanks, but you do want a few solid territories and places for weaker fish to duck out of view.

• Substrate: sand is my pick (easy on mouths and gills, and they look natural over it)
• Rocks: a couple of stable piles or shelves, not a wall of rubble
• Hiding spots: caves and gaps large enough for a female to get away
• Lighting: moderate (too bright with no cover can make them jumpy)

What to feed them

These guys do well on a meaty, higher-protein diet, but you do not need to feed like you are fattening up an arowana. I use a quality cichlid pellet as the base, then rotate in frozen foods a few times a week.

• Staple: medium/large hap pellet or granule (not super high-fat)
• Frozen: mysis, krill, brine shrimp, chopped prawn (sparingly)
• Occasional: high-quality flakes as variety
• Skip: mammal meat (beefheart) and greasy foods that foul water fast

Feed smaller portions once or twice a day instead of dumping a big meal. With Victorians, clean water and steady feeding does more than trying to push growth with heavy feeding.

How they behave and who they get along with

Expect classic hap behavior: posturing, chasing, lip-locking now and then, and a lot of "I own this side of the tank" energy from mature males. In a roomy tank with multiple females and a few distractions, they are manageable. In a cramped tank, one fish can turn it into a war zone.

• Best groups: 1 male with 3-5 females (or more) to spread attention
• Avoid: two similar-sized males in a smaller tank unless you have a lot of space and extra hiding structure
• Good tankmates: other medium-large haps/peacocks with similar temperament
• Not great with: timid community fish, slow fancy fish, or tiny species that look like snacks

I have the best luck keeping them with other open-water cichlids rather than mixing them into heavy rock-dweller setups. They like room, and they like knowing who they can boss around. If everything in the tank is a bruiser, they stay on edge.

Breeding tips

They are maternal mouthbrooders, so breeding is very doable if you keep a harem. The male will claim a spot (often a flat rock or open sand patch), show off hard, and the female will pick up eggs and hold them.

• Trigger: stable warm temps, good food, and regular water changes
• Setup: give the male a clear display area plus rocks that let females escape
• Holding: females usually hold around 3 weeks, sometimes a bit longer
• Fry: newly released fry take baby brine shrimp, crushed pellets, and powdered foods

You can let a holding female carry in the main tank if your stocking is calm and you have lots of cover, but I usually move her to a separate tank if I actually want numbers. In a busy hap tank, fry tend to disappear fast.

Common problems to watch for

Most issues I have seen with Edward cichlids come down to stress from crowding, messy water from heavy feeding, or mismatched tankmates. If you keep the water clean and the social setup makes sense, they are pretty tough fish.

• Bloat-like symptoms: pinched belly, stringy poop, hiding and refusing food (often tied to stress and dirty water)
• Beat-up fins and scales: usually from one dominant fish harassing the rest
• Ich after new fish: common if you add fish without quarantine and the tank is stressed
• Spooked jumping: especially during lights-on, maintenance, or after rearranging decor
