I rescued a fish yesterday, no clue what kind of fish it is. They said it was possibly a goldfish, but the tail looks slightly different from a gold fish. It was in a tank that had not been cleaned out since November, the filter, or anything else had not been cleaned out since November. The whole tank was covered in algae, the filter was backed up, there was rocks in the tubes that hang into the tank, all the fish died except for this one little fish. This poor fish was laying on it's side, if you tapped the glass he would try to swim. I rescued him and brought him home with me, I put him in a clean tank, with a light, heater, filter, gravel, and an artificial plant. When I put him in this clean tank he immediately started trying to swim (opposed to what he was doing, just laying on his side in the other). Sometimes he swims straight up, but other times it's swimming on it's side or upside down. It's still eating. I tested the water in the other tank that it was in..the levels of everything in it were so high that it went way past the guide colors on the test strip bottle. The fish has a few greenish-darkish spots on him, but they're getting less, some of the algae fell off of him into the clean water. I also put a tablespoon of aquarium salt in the tank last night and a lifeguard tablet. I've also treated the water with water conditioner before i switched the fish into this. I'm attaching some pictures of him, maybe someone knows what kind of fish he is. (Pictures just taken with a camera phone, didn't want to freak him out with a camera flash)
Does anyone at all know what I can do to save this poor fish? I called a local pet store and all they said was 'throw him in a bag in the freezer, he'll just go to sleep'. I told them 'I am not killing this fish.' I'm not going to kill a fish that still has a chance. I was told that possibly his equilibrium was maybe off, I've seen online about swim bladder, his belly doesn't look swollen or anything though. Does anyone at all have any suggestions on saving this poor little guy?
