I just went through moving my 60g tank from my rents house to my new house i moved 50% of the original water and took the 4 fish that where in there full size convict, pleco 12"+, some small breed pleco and my 12"+ tiger oscar. all of the fish seem fine except the oscar he's coming up on 3 years old he was in a five gallon bucket i cleaned out well with aquarium salt for maybe 2 to 3 hours. I even rigged a magnum HOT filter to the bucket to give him air and circulate the water its been 2 days now and he wont eat anything and he's just sitting on the bottom. All the other fish seem fine and i'm wondering if maybe he's been this way for awhile cause my father was suppose to be there care taker for the last 6 months but i know he wasn't doing very much for them. Also wondering if he has a peracite or something. i'm going to the local fish store tomarro to get the water tested and ask there advice.
