I've been keeping reef aquariums since 1999 and wanted to set up another tank to get back to my cichlid roots. Back in the 80s I kept a large managuense and I'm getting nostalgic. I have room in the house for a 120 gallon, four foot long tank, and would like some suggestions for interesting medium sized cichlids or perhaps a single larger "wet pet" cichlid with personality and color. I know those dimensions are way too small for a full grown managuense. Thanks.
