We have 2 veil fin oscars. Our old one is swimming around and he's doing great. But our new one is laying on his side at the back corner of our tank. He was great yesterday. But this morning he wouldn't come up for food and he's just been laying there all day. His gils are moving and he looks around, and he scooted away when i stuck my hand near him so he's alive, he just doesn't seem to be feeling so hot.
Any thoughts? I did a water test and ammonia and all the other great stuff is within the normal ranges. And as previously stated our other oscar is fine. They're both in a 55 gallon tank and the temperature is 79 degrees f. We aren't too sure on what we should be doing for him, if anything at all. Or if maybe he's just chilling back there. Any information at all would be greatly appreciated!
