cardinal tetra is having trouble swimming straight?
one of my 6 cardinals is having trouble swimming straight he tilts to one side like he's laying flat b4 straightening himself out again, pretty much continually. And I just caught him resting on the bottom but he swam off when I tried to fish him out.
Did a water change, cleaned filter last night and just added water conditioner. (due to a mistake the water change didn't get done last week so it has been a fortnight since the last water change but when I checked the water b4 changing the nitrite, amm. levels were both 0, checked just now and all is ok still - using liquid testing kit)
There are no other visible signs of sickness on the fish and his neon blue stripe is still shining.
What should I do just leave him in, take him out away from the other fish, I've only got the one tank so unfortunately i can't keep him separate for long.
hope you can advise.
