MFK members: I really do not want to lose this fish and I need some advice. I've had this beautiful fish for about 6-7 months. Here is what has been going on. I moved this GEO out of his 50 gal about three weeks ago as he was getting thumped by another Geo. Sur. At that time he was eating really well and was very active. I moved him to my wifes tank of tropicals, (40 gal) to give him some peace and he was doing really well, eating vigoursly etc. and chasing most of the fish. About a week ago he has stopped eating, does not sift, hides all the time and is very scetchy. I moved him to a 10 gal rehab tank in my garage that I keep running continuesly and he is not improving. His eyes are clear, no red gills or lesions, anal area looks fine. I'm thinking it could be internal. Below are his water parameters, (I just tested prior to opening up this thread) Any comments or suggestions would be appreciated.
10 gal rehab tank
Temp=78
Amonia=0
Nitrite=0
Nitrate=<.20
PH=7.6
