My tiger oscar which I have had for about 2 years and is about 10" is unable to swim, he lives in a 80 gallon tank along with a a Severum and a blue crayfish, he's always been healthy but about 6 weeks ago he lost the ability to swim to the surface, it's like something is holding him down, he doesn't have no obvious sign of causes e.g. Bloating or anything just a few rubbing marks now cause he's on the sand constantly, now and then when I feed the fish he kinda forces himself up and takes a mouthful but sinks straight back down like a rock, he doesn't seem to be in pain, I've tried salt baths and feeding peas but nothing seems to be helping him, I think if there is no way of sorting this I may have to euthanise him cause it's not fair on him, so if anyone has any ideas that would be great?
Cheers in advance
