Planning your aquarium

The library starting point is 55+ US gallons. Plan for the approximate 10-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

  • Maintain stable, species-appropriate water and provide a mix of cover and swimming room.

Food and feeding

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: The size and aggression mismatch is unsafe.

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