Update: I'm afraid to say it
but things *might* be looking up...
Nobody's eating still and I lost another fish yesterday. I figured what could it hurt? So I decided to start antibiotics and see what happened.
Well, no one has eaten anything still that I can tell. My pleco, who has been dubbed "Spartan" since he's the valiant warrior battling for his existence, (my 14-yr old is into history--especially of war), was hanging around last night--which has been rare and this morning when I got up he was attached to a rock with his fins all fanned out. Yea!
I hope these are good signs and he'll eat something substantial soon. I assume he's eating someting or he surely would have starved in 7 days. I've tried peas and bits of potato in addition to the usual shrimp pellet and algae disc. If I can only get him to eat I can hold out hope.
