Does anyone have any experience with these? I picked him up on a whim as I was getting some feeders and seen him in a tank. It seems to have quit the personality and swims around with a purpose but how will it do in my 450 gallon with these fish: pair of albino oscars,4 black arowanas, 5 strigata pikes,3 lenticulata pike,3 ornate bichirs,pair of uaru,5 geophagus surinamensis,4 blue botia,2 sailfin plecos,2 gold severum,1 giant vampire gourami,2 cuban cichlids,2 clown knife,1 tire track eel, 1 black spotted eel,3 malawi trout and a striped raphael catfish. These fish are all decent size except for one gold severum which is about 4 inches. These fish all coexsist in the same tank now with no problems but what would happen if I put the snakehead in? Or am I just asking for trouble? Does anybody know how common the maruliodes are?
