So, I've got my African tank up and going, all is well. I had picked up a beautiful 5 inch BGK at PetSmart (had to save him from "darla's) (she's the little brat in Finding Nemo).. I'm gearing space and $ wise for a breeder tank for him, (teacher pay, 55g +all necessaries + fish took funds for now); for now the Ghost (Mack) is in the Rift Lake tank (4 2in yellow labs, 3 2in cobalt blues). I've been reading conflicting info--I do know that the pH, kH, gH levels are probably too high for him (need to get addditonal test kit) but alot of people seem to keep a South American with Africans just fine. What do you guys think? He's been in a week with them (crushed coral topstrate), separate controlled feedings, acting normal, etc., but will the higher levels stress him out too much? I can always sell something and get the money for another tank ahead of schedule if I'm lucky. . . thanks, ~renee
