Iris hap

Where they come from

Haplochromis iris is a Victorian hap from the Lake Victoria basin in East Africa. Think rocky shorelines with pockets of open sand and lots of small invertebrates drifting by. Like a lot of Victorians, they are a bit of a conservation story because of habitat changes and past introductions, so I treat them as a fish worth keeping pure and healthy.

Setting up their tank

Give them footprint over height. A 55 gallon is a nice starting point for a group, and a 75 makes life easier. I keep rock piles to break line of sight, but leave open sand or fine gravel for pacing and courtship. They are jumpers, so a tight lid is not optional.

• Temperature: 75-78 F (24-26 C)
• pH: 7.6-8.2; hard, mineral-rich water (KH 5-10, GH 8-15)
• Filtration: strong and steady; aim for 6-8x tank volume per hour
• Water changes: 30-50% weekly; they color up and behave better with clean water
• Substrate: sand or fine rounded gravel; they pick at it a lot
• Scape: stacked rocks/caves plus open swimming lanes
• Lid: tight-fitting, no gaps

What to feed them

They are insectivorous-leaning omnivores. I do a quality small pellet as the staple and rotate in frozen foods. Two small meals a day is plenty; they beg like Labradors, but their guts do not love heavy feedings.

• Staple: 1-2 mm high-quality cichlid pellets (omnivore/carnivore blend)
• Add-ins: frozen mysis, daphnia, brine shrimp
• Greens now and then: spirulina flake or a veggie-based pellet
• Fry/juveniles: crushed flake and freshly hatched brine shrimp

How they behave and who they get along with

Semi-aggressive and very cichlid about territory. A colored-up male wants a little stage to dance on and a few females to impress. They are quicker than many Malawi fish and will hold their own, but mixing with hyper-aggressive mbuna is asking for shredded fins.

• Best setup: 1 male with 3-6 females to spread attention
• Tankmates: other Victorian haps of similar size and temperament if you are not breeding
• Bottom crew: Synodontis catfish work, but they will snipe fry
• Avoid: mbuna bruisers, large predators, and look-alike species that could hybridize

Breeding tips

They are maternal mouthbrooders. Give the male a flat rock or small clearing, and he will do the rest. Females will hold for around 3 weeks, and you will see the classic bulging throat and that quiet, careful way of swimming.

• Ratio: 1 male to 3-6 females
• Courtship: male flashes and shimmies over a rock or patch of sand
• Hold time: typically 18-25 days depending on temperature
• Fry care: if you want numbers, move the holding female to a small, quiet tank near the end of the hold and let her spit naturally
• First foods for fry: baby brine shrimp, then crushed flake
• Recondition the female after release with small, frequent, high-quality meals

Common problems to watch for

• Bloat: usually from stress, dirty water, or rich foods. Catch it early, lighten feeding, big water change, consider metronidazole if they stop eating.
• Beat-up females: add more hides, rebalance the ratio, or pull the dominant male for a week.
• Jumping: they launch during spooks and chases. Keep every gap covered.
• Water quality swings: Victorians show dull color and clamped fins fast when nitrates climb. Stay on that weekly change.
• Misidentification: H. iris can be sold under various names. Buy from keepers who label lineage if you care about breeding.
