suddenly!, but when i feed him, he goes up to eat, normally., and now, stays at the bottom, but now, with the tail a little bit more relaxed, and on the side, like dolphins in small tanks.
i guess it´s better after some water change (only 15% aprox) I ´m gonna tray to make another 15% to see what happen. About cycling, i guess i´m in trouble, cause i have to much nitrite (near 10ppm)
thanks a lot
