I have a 150 gallon SA community tank with 5 Geophagus, 1 Uaru, 2 Turquoise Severums, and 4 Silver Dollars. My water is soft, slightly acidic, 0 nitrite, <20 nitrate.
I have had some strange deaths of my Geophagus in this tank. I had a large G. Surinamensis several years ago who suddenly went wild and rocketed around the tank and hitting the canopy. I witnessed 2 G. Jurupari die the same way. I heard some crashing tonight and my remaining Jurupari was bruised and floating upside down, but seems to be recovering.
What is going on? Could it be hole in the head disease, even though no pitting is evident?
I perform 40% water changes each week, usually on Saturdays.
I sometimes see the fish rubbing against the sand, but haven't seen any other problems.
My fish are fed on a diet of NLS and occasional feedings of frozen bloodworms.
Any suggestions?
Mike
