Diet

In captivity it thrives on a varied diet of high-quality pellets, frozen or live foods such as brine shrimp, daphnia, and bloodworms, with an emphasis on protein-rich offerings to support health and coloration.

Community Compatibility

Best kept either alone or as a pair/trio in a species-only setup, as it can be territorial and is not ideal for general community aquaria.

Good to Know
