I have just treated my fish with "clout" for itching on the rocks in the tank. this did not work . What do I use next ? They also yawn and dart about the tank . The itching will start on new fish after only a short time in the tank. Also do fish yawn if they have some kind of parasite? ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
