The past two days Bernard has been acting very sluggish. Usually he's very active and curious but this has now become his regular position.
There have been no changes in his diet and the water parameters are as follows
He only moves around when he has to breathe. There are no visible marks on his body and no bulges or bloating. His gills move very slowly. His water temp gets pretty low at night but this has never been a problem before and the weather here is always the same. His water right now is at 72 and it doesn't change much from there. I have no idea how old he is but three days ago he was working on bubblenests nonstop so he's not THAT old. I'm really starting to worry. He's never acted like this before. I tried a salt bath earlier today to see if that might help but he's not responding to it. All I have is aquarium salt and bettafix at the moment. Any ideas as to what it might be??
