Hi my 3-4 year old green terror seems to be knocking himself out unconscious now and cant seem to figure out why. Ive checked the ph levels, ammonia levels nitrate levels everything and its perfect. Theres also no parasitic or funal in my tank either we lost our female from doing the same thing by knocking herself out i dont want to loose my big man. Can anyone help.
 
What exactly is he doing? Does the tank have enough oxygen?
Hes has plenty of oxygen to his tank. I also run 5 other fish tanks in my house and his seems to be the only one im having trouble with. He starts to swim around the tank really fast the zooms straight up to the lid with force and knocks himself out. He goes stiff for a few minutes then hes back to normal again.
 
Sounds like hes trying to get out of the tank. Never had a fish do that but my guess would be something about his water or the tank hes not liking.
 
Yeah i dont know either my partner works in a fish store and even he is confused as to why he is doing this aswell.
 
How are you approaching the aquarium? Is there high traffic near it's aquarium? Check your heater?

What size tank? Have you tested your water parameters? Checked heater for current leakage? Tried a large water change? Hope you get it figured out.
