They are tough, I catch them from water where almost nothing else will live. The black spotted ones occur naturally in normal populations, I think they occur in response to stress but I can't prove it. it seems that the worse the conditions are the more of the black spotted males you see. I know of one population where males occur at about 10 times the normal rate.
I'd eventually upgrade a BGK to something bigger than a 30, but it would work for a little whileBottomfeeder;2154339; said:uhhh not to be a hippocrite but a few Black Ghosts in a 10 gal in my lfs. i read they can be in a 30 gal and are easy to care for. i put gambusias on hold for a while...
