Well ive had bad experiences with cichla in the past and haven't been able to get them to feed. I now have a 12" Mono who has a good body weight and ive had him for a day nearly two, and ive tried with floating pellets, sinking pellets, mussle, prawn and squid and he hasn't eaten anything. Hes tail is also a little white and fraid around the edge the same as my new big geophagus brasiliensis (Different tank) ive added a little salt does he need time? (He wasn't fed on feeders initially)
