Well I'm loosing fish and I'm not sure why. I have a 30 gal with Aferican Chiclids had 10 now 8 (they are small not full grown only inch long once bigger moving some.) I have had Chiclids for 15 years just started the tank again 5 months ago. I've tested the water and it is all normal. I don't over feed and only feed them every 3 days, and the strange thing is that they look fine and healthy. The tank is established so that's not it, I cleaned it about 3 weeks ago was going to clean it this weekend. No abnormal alge growth, temp is 76-78. Any Ideas? Would hate to keep loosing them since they are not excatly cheap ya know.
