I "could" be interested in up to 6 depending on price and whether i can bare to part with some fish i already have (no space for any more tanks). Breeding zebras is something ive been thinking about for a while since they are about to be taken off importers lists and face extinction in the wild due to habbitat loss (the government there plan to build a hydroelectric dam in their spawning grounds). With the prices of zebras set to rocket again in the near future (some are talking of prices like £180 per fish) the more captive bred fish available the lower this price can be, also it makes a nice bit of cash in my pocket
