My male marble had his tail bitten by my arowana about 2 weeks ago.
I've since got rid of arowana and at the time Rays tail looked fine other than few thin tears in flesh, but it's getting progressively worse.
It looks like the cartilage has been snapped but flesh still intact as it's now permanently badly bent.
I'm aware that tails don't regrow or repair so if I leave it will it just drop off or Could it deteriorate so should I chop the affected part off?
Any comments appreciated.
