My cichlid has to live alone because the people and the pet store that had him previously had him living alone because they said he would attack any other aquarium inhabitant. I think of him more as a mistreated fish I rescued than one I bought. I love my mean little buddy (named Chicken). I just worry about him being bored. Chicken has rocks, a clay pot, driftwood, 3 marimo and plants, and an aragonite and gravel substrate. I'd love any and all ideas about cichlid enrichment.
