I've had him for about a week and hes just starting to come out a bit. Hes an awesome fish! Hes taking pellets and new era sinking cichlid foods and OFC i have fed him some live.
There is however (as usual with me) a couple of things. A lady bought the nicest and largest raindow shark i've ever seen into my shop and i want him. He'll never survive in the big tank so i was thinking of adding him to the perch tank. Think this is a bad move?
Also since moving the tank around i've disturbed the dormant snails again so i have another outbreak. I think i'll try a single adult yoyo loach. But i'm not 100% sure that the loach wont be a bully for the perch, will he look after himself? I've found predatory fish to sometimes be a bit wet (excuse the pun) when it comes to backing themselves up.
I've decided that this is HIS tank. No other predators
I kept a younger rainbow shark with my ctenopoma (spotted climbing perch) for about a year or so without any incident in a 55gal. After moving the ctenopoma to a separate tank the rainbow shark got older, larger, and more aggressive. So, I think it all depends on the fish but erring with caution I would advise against it.
