Greg, Your A. sp. Miuá are acting like my Miuá. Your water conditions are not suitable for breeding, so they are behaving like non-breeding Apistogramma. I never was successful at breeding this species. It seems that A. sp. Miuá require very acid (~ pH 4!) and very soft water before they will reproduce. Your female viejita may have gill parasites. I would remove her to a hospital tank and treat her separately. Mike Wise Grzegorz Prusinowski wrote: > 2 questions concerning 2 species, bu they swim together in > one tank.
