My experiences agree pretty much with what David wrote. Really soft, acidic (pH less than 5) and quite warm worked for me. I started out with 5 juveniles, turned out to be 3+2 which soon was 1+2 in a 150-liter tank (40 gal). Heavily planted but with fairly dim lighting. When the conditions were right they turned out to be quite easy to breed. Took care of the spawn impeccably, no problems wse. I also have friends who have bred them in more neutral, but still soft water. My guess is that it has to be to different populations living under different conditions in the wild (mine were originally wild caught, of the red variety if there really is a difference). Does anyone know of a paper or a source for the change in Genus to Apistogramma? /Fredrik ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
