Cichlids: Types, Care & Tank Planning

Cichlids are a family of roughly 1,800 accepted species, not one care type. Before buying, identify the exact species and source, then compare adult measurement, usable tank dimensions, social system, territory, tested water, diet and an exit plan. No family-wide minimum tank, water range or tank-mate list is safe.

This is the Rio Madeira locality of Agassiz's Dwarf Cichlid (Apistogramma agas. rio madeira), a regional form named for the great Madeira River of the Amazon basin. Each A. agassizii locality carries its own character, and this one offers the elegant lines and engaging manner that make the species a long-standing favourite, growing to a useful 7 cm.

Warm, soft, acidic water is the foundation of good keeping here. Hold the pH between 5.5 and 7.0 with hardness kept low at 0-10 dGH, and run the tank a touch warmer at 25-29°C. A minimum of 75 litres gives a planted set-up the space a male needs to hold a territory and a settled pair to display naturally, with driftwood and shaded cover doing much of that work.

It is a carnivore that feeds best on small meaty frozen and live foods presented low in the tank, where it forages along the substrate as a bottom-dweller. Behaviour is semi-aggressive and it can become territorial, so a roomy, well-structured aquarium keeps the peace and lets its personality shine without friction between individuals. At a touch larger than many of its cousins it makes a particularly bold display fish for the genus, holding its ground with character. Ease new arrivals into your parameters gradually so they take up a territory and feed with confidence, and keep the layout broken up with cover so individuals can keep a respectful distance; a well-conditioned fish settled into stable, soft water shows the cleanest lines and the most assured behaviour.
