Very small fish (about 5 cm adult length or less)

Keep a group of twenty or more with dense cover and a base of at least 60 × 30 cm.

Keep a group of twenty or more with dense cover and a base of at least 45 × 30 cm.

Provide algae-covered surfaces and stable water; protect snails from predatory tankmates.

Use a mature tank with established biofilm; confirm actual feeding and supplement food.

Provide dense cover, stable warm water and room for fish to retreat from displaying males.

Fin nipper — avoid with long-finned tankmates

Keep a substantial group; avoid slow or long-finned fish. A community needs more space than the minimum species setup.

Maintain stable warm water and provide cover, open sand and a base of at least 60 × 30 cm.

Fin nipper — avoid with long-finned tankmates

Maintain strong oxygenation, water movement and mature biofilm on rocks.
