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 library suggests a group of at least 6. Count every individual when estimating stocking and swimming room.

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

Tank setup and behavior

  • Provide bottom space, suitable substrate, and accessible hiding places.
  • Include planting or cover without removing all open swimming space.

Use soft sand or smooth substrate with caves, leaf litter or planted cover; leave room for the entire social group.

Food and feeding

Food options: Sinking pellets, Frozen bloodworms, Repashy-style gel food.

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 Goldfish: Their preferred temperatures overlap poorly for long-term care.

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