I added a few Flag Cichlids to my 55-gallon tank with other peaceful fish. They’ve been active and calm, eating well on a mix of flakes and sinking pellets. The plant-based food helps keep their color vibrant. Great addition to a community setup.

The juveniles arrived healthy and seem to be adjusting well. I feed them a balanced diet with some algae wafers and vegetables. They don’t chase other fish and stay in the middle of the tank, which is perfect for a shared environment.

After a few weeks, the cichlids have grown nicely and are active without showing aggression. I noticed they prefer food with plant matter, so I’ve adjusted my feeding routine. They look healthy and colorful.
