bloody heck, talk about trying to put me off! haha
i think things like dennisoni barbs would have some form of a chance as they do get to a decent size and are extremely fast swimmers and from what i know hardly ever go near the floor of the tank. my frontosas are only 4" at the moment but need the hard al;kaline water. the maidenhead aquatics near me have about 3 at about 10" for a reasonable price so i might try them.
i was going to ring a guy today about a group of them black bar dollars, the ad was on the calssifieds, 11 6-7" for £100 ono, they look nice and he has them in with a couple of leo's, dats and an arowana. think his leo's are only 6" though!
what about discus? whats the chance of them being food? if i got a load of them it would brighten up the tank wouldn't it!
also got to remember i have 9 rotkeil severums upstairs growing, waiting to go into the big tank, and 2 more pink tailed characins, and 3 more polypterus!
what are peoples thoughts on the Platystomatichthys sturio?
