Planning your aquarium

The library starting point is 30+ US gallons. Plan for the approximate 6-inch adult size and the species' normal activity, not just its current shop size.

The minimum group count is not a compatibility recommendation; assess temperament, sex, territory, and tankmates.

Mixed-species aquariums may need substantially more space. Tank length, adult behavior, filtration, and hiding spaces all matter.

Tank setup and behavior

  • Break up sightlines with plants or hardscape to create distinct territories.

Very territorial, especially during breeding.

Food and feeding

Food options: Cichlid pellets, Frozen foods, Vegetable matter.

Use appropriately sized, complete staple foods and rotate suitable foods for variety. Feed modest portions and remove uneaten food.

Tankmate cautions in the checker

  • Avoid or investigate Betta Fish: A territorial convict cichlid can seriously injure a betta.

These are selected rule-based cautions, not a complete compatibility assessment.
