Can Convict Cichlid Live With Neon Tetra?
No, convict cichlids are highly aggressive cichlids that eat neon tetras and terrorize any small fish in the tank.
Why
- Convict cichlids grow to 5-6 inches. Neon tetras stay at 1.5 inches and are easy prey for a fish of that size.
- Convict cichlids are among the most aggressive Central American cichlids, especially when breeding.
- Water parameters overlap (75-81F, pH 6.5-7.0), which makes the pairing look viable on paper.
- Convicts are prolific breeders and will guard fry aggressively, attacking anything that comes near including tetras.
- Even outside breeding season, convicts are too aggressive and predatory for small fish.
What could go wrong
Tetras get eaten one at a time over weeks, with losses accelerating if the convict breeds and needs to protect fry.

Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
Convict cichlids do well with other large, aggressive cichlids or catfish. Neon tetras do well with corydoras or small peaceful community fish.
