I've got 2 one solid about and one with the gold spots VERY aggressive fish but it is possible to keep them in a community I've had mine for about 3yrs. now and they've been in a CA/SA cichlid community ever since they have taken a few fish out over the years tho they are like ninjas DON'T PUT UP A FAIR FIGHT because they ONLY play in the darkness of night VERY COOL FISH tho IMO
they eat anything meaty: live (ofcourse), earthworms, nightcrawlers, freeze dried krill, shrimp pellets, sinking carnivore pellets, etc.....
they are slow growers putting on may 1-1.5in. a year MAYBE 2in.
VERY SECRETIVE COOL FISH to own
