For the last few days he has been hanging around at the surface looking a bit listless, I put this down to him being bullied by a tankmate (who we removed yesterday). However, he is still hanging around at the surface, and just now he was swimming around on his side and sort of just drifting and flipping over. Just now he tried to swim to the bottom of the tank and rolled over onto his back and over and over again as he was heading down, it was quite disturbing
The tank stats are
Ammonia - 0
Nitrite- 0
Nitrate- 10
When he's not rolling over and over he just seems..I dunno, tired. Like he can't be bothered to swim around anymore! He's just drifting almost vertically with his head at the surface right now.
Any advice? There is no sign of any parasites, fungus, damage to fins etc. If it wasn't for how he's acting I would think he is in perfect health! Is it possible he's swallowed air or has a swim bladder problem? Could he be constipated?
please help
thanks in advance.
