As the title states i have a sick acarichthys heckelii.. he is always on a 45 degree with his head being the top... he wiggles kind of like a snake as if he is struggling. occasionally he sits on the bottom of the tank. He doesn't eat and is breathing faster than normal. He has been like this for over a week now. No one else is the tank is doing anything out of the ordinary just the largest heckelii. i haven't added any medicine as i have no idea what it can be... any ideas on what it could be or what could help? thanks!
