I have three rotpunkt apistos in a twenty gallon aquarium with other fish and some plants. The male is breathing heavy and looks like he might have a small cut just above his gill plate. I have been trying to use DYI co2 but it just won't work. There is no surface agitation because I was trying to keep the co2 from dissolving into the atm. Should I forget about the co2 and put my spray-bar back in? If this guy dies, I'm pretty sure one of the others is a male (juvinule colors), but I would rather keep this dominant male if possible. Any suggestions? JJJJJJJJJJ JJ JJ JJ JJ JJ JJJ ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
