First off, if your Altispinosa's are of age. They are not going to spawn with Kribs and Convicts in the same tank. Also get that large pleco out too. Once you have just the 5 altispinosa's in the tank by themselves, you should see some activity. Your water parameters sound fine, but you never mentioned what size tank? Try moving everything out and see what happens. John ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
