I'd go $100 thats it.
And once i aquired some i'd make it my priority to breed them and get some fish distributed in the hobby (i'd sell them for a low price). If you buy high just to keep.......oh yeah the diminish in the wild. But i acctually want to get the species going again. I'd devote my hobby to breeding them for a while......i really would. Hardly any other fish, just the zebs.
