An omnivore with almost no off switch
The convict cichlid, named for the black bars striping its grey body, has a reputation for toughness earned partly at the food dish: it eats readily, grows fast, and breeds in conditions that would discourage fussier cichlids. In the wild it takes insect larvae, small crustaceans, algae, and plant debris from Central American streams, and the aquarium menu should echo that mix rather than lean entirely on any one item. A good staple is a small cichlid pellet or sturdy flake taken daily, but a convict fed only dry food, only protein, or only leftovers will show it in washed-out barring, excess weight around the belly, and water that deteriorates between changes.
Building the weekly rotation
Across a week, alternate the staple with two kinds of additions. The plant side can include crumbled algae wafer, blanched zucchini or pea flesh with the skin removed, and spirulina-bearing flake, all of which support digestion in a fish inclined to gorge. The protein side, offered a few times a week rather than daily, suits thawed daphnia, brine shrimp, or mysis, and a small earthworm piece for a large adult makes an occasional high-value addition. When a pair is guarding eggs or wrigglers, keep the rotation steady and slightly generous, because both parents fan and defend for days while eating in snatched turns at the edge of their territory.
Portions for a fish that always says yes
Frequency follows the same rule as variety: adults do well on one or two measured meals a day, juveniles on two or three smaller ones while they are growing, and every meal should be gone in about two minutes. Deliver at least part of the food in sinking form and scatter it, because convicts feed through the water column and will excavate the substrate afterwards, sifting mouthfuls for missed crumbs and redecorating the tank in the process. Feed breeding pairs near, but not inside, the nest corner, so parents are not forced to choose between defending the brood and eating.
Tankmates at the same table
In a community setting the convict is rarely the fish that misses out; it is the reason others do. Its confidence at feeding time, backed by genuine territorial aggression once a pair forms, can leave slower cichlids and bottom feeders thin while the convict thickens. Scatter food at both ends of the tank simultaneously, provide sinking portions after lights dim for nocturnal bottom dwellers, and watch body condition across the whole tank rather than judging the feeding routine by its boldest member.
When eating changes mean something else
A convict that refuses food is unusual enough to take seriously. A female sitting tight in a flowerpot or cave may simply be on eggs, and a subordinate fish may be avoiding a dominant pair's feeding ground, but refusal paired with clamped fins, heavy breathing, white stringy waste, or a swollen belly calls for water testing and prompt advice from an aquatic veterinarian or specialist retailer rather than diet experiments. Appetite also dips when temperature falls below the fish's comfort or after a major rescape disturbs established territory, and usually recovers as the tank settles.
Keeping one portion policy in a house of feeders
Convicts convert every visitor into a feeding opportunity, so the written routine, not the fish's confidence, should govern what goes into the tank. Noting the day's meals where everyone can see them prevents the slow drift from two measured feedings to five casual ones. KinsLe Care Teams supports that discipline by assigning each convict feeding to a specific helper and recording completion with a timestamp, leaving the fish's begging as entertainment rather than instruction.
