For the last 3 days my Green Severum has just been sitting on the bottom of the tank.
He comes up to eat and swims around for about 20 seconds then he just goes back to sitting at the bottom. Then my other Severum comes next to him and just hovers over him. Both Severums are about 3 years old.
He is eating and the tank parameters are normal, 0 Nitrite, 0 Amonia, and about 12 Nitrate. The tank has been set up for over 2 years and all of the other fish are fine. Every week i do a 50% water change and vacuum the gravel. It's a 125 gallon with 2 Severums, a Green Terror, a pair of Convicts, an earh eater and a Blood Parrot. They are all fine.
Any ideas?
