Hello,
I've recently started my first tropical tank. At the moment i have 5 neon tetras in there. Today i noticed that one of them is losing its red colouring and was wondering if it could be neon tetra disease?
He's swimming normally and doesn't seem to be having any problems at the moment. Could it be that he swallowed some air while trying to feed like someone said earlier in the thread? What should i do?
Thanks
Ron
