Planning your aquarium
The library starting point is 20+ US gallons. Plan for the approximate 4-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
- Secure the lid and protect gaps around equipment and cables.
