Overview
The filter-feeding cichlid is a gentle, disc-shaped cichlid for the middle of a calm, soft-water tank. It is a fish for a keeper with some experience.
Caring for the filter-feeding cichlid
Keep filter-feeding cichlids in a small group, since they are social, peaceful fish. Give them at least 79 gal (300 L) with open swimming space, a soft substrate, gentle flow and some wood or leaf litter.
Keep the water warm and soft to neutral, at 75 to 82°F (24 to 28°C) and a pH of 5.5 to 7.2. Feed frequent small servings of live and frozen foods they can strain from the water, such as daphnia, cyclops and baby brine shrimp.
The filter-feeding cichlid is so mild that it needs equally polite tank mates, ones that will not outrace it to food or bully it. Its calm nature is easy to take advantage of, so feed carefully.
Like related cichlids, it is expected to guard its young. Breeding it is of medium difficulty.
Good to know
The filter-feeding cichlid, Chaetobranchopsis orbicularis, belongs to the cichlid family. Its rounded, deep body gives it the species name orbicularis.
In the wild
Chaetobranchopsis orbicularis lives in the floodplain lakes of the lower Amazon, off the main river. The water there is still, warm and rich in plankton, and the fish drifts through these quiet backwaters as it filters its meals.
