Those who survived get their color back but are quite "quiet", not the cichlidish attitude they used to, and still ventilating quite fast. There is a good water flow and enough ventilated and it's a specific tank, not overpopulated (about 30liters/ram)[JMS] > Bob Dixon > > ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
