The Bicolor Dottyback is striking with its purple and yellow coloration. It’s active and territorial, so I made sure to have a large tank with plenty of hiding spots. It eats brine shrimp regularly and keeps the bristleworms under control. A bold addition to any reef tank.

I was cautious about adding this fish due to its aggression, but it’s actually manageable in a 30-gallon tank. It doesn’t harm other fish as long as they’re not too small. The color contrast is impressive and it’s a great visual focal point.

The fish arrived healthy and quickly settled into the tank. It’s a predator of nuisance bristleworms, which has reduced my cleaning time. I feed it brine shrimp twice a week and it’s always active.
