Today I brought home a 10 inch silver who has taken a beating from a big one..for the last week she was in the lfs, in a tank, I believe with some sort of antibiotics....anyway..her barbels are gone, one eye is totally cloudy, she looked awfull..she has improoved somewhat and is eating pellets... as said I brought her home, put her in a big tank, alone...now heres what makes me wonder..she swims majestically, for a while, then she lied down, sometimes even like a piece of cloth on the ground or draped over bogwood..then she started swimming again..always near the bottom of the tank , and she hides in the middle of the bogwood, of which I have tons, really hidden and peeking out..then she takes another swim, near the bottom, and hides again...tens of aro's of every kind ( except afrivcan ) never had this behaviour before. any hint? any suggestion, please?
