Problem with tail

[mrt]

Seen this tail issue before?



I suspect he is scratching the tail against the piece of wood in the tank, do you agree?

Edit: if you got problem to see the full size pic it is here:

What are the tank mates?

What are the tank mates?

Geophagus, they are only picking sand from him, never seen them do any damage.

How long has the ray been in the tank/how big is ray? If the ray was added fairly recently I would suspect the other fish. Rays are for the most part passive fish and can easily be picked on by other fish. I would add some salt to the tank to aid with healing. Also weekly water changes at least.

looks like it could be the beginnings of tail rot to me. or possibly a tank mate chewing on it.

Its been in the tank for about 9 months, and with the Geophagus for about half a year. The ray has grown a lot and I think it got too crowed due to the piece of wood I got. I've removed it now and will add salt.

Thanks

Looks like it's getting bitten. I haven't had a ray rub it's tail on something before. The only other thing I can think of is if the ray goes up and down the side of the glass alot and lands on it's tail.

id take the wood out. see if that helps since u think it might be the cause. then i would watch very carefully the tank mates to see if there doing anything. sometimes a tank mate will be fine with rays but things can change. keep ur water clean, keep up on water changes an keep the the temp bumped up a bit. if it doesnt seem to get any better i would try and maybe separate the tank mates. just try one thing after the other an try an pin point what might be the cause.

He likes to do that.

No improvements on the tail, but it is not getting any worse either. Do you think it should have healed during these two and a half weeks?

Also I got a related thread here about my ray and the Geophagus:

I've seen they touch the tail now and then but it is not often...
