Has anybody got advice for treating an injured Black Ghost. I added him to my tank yesterdy and this morning he has "lost" most of his tail section (both white banded areas). I use a tablespoon of salt per 20litres and have never had any signs of fin-rot in the tank. I dont think any of his tank mates would have caused this injury and can only assume the fish has snagged himself somewhere. If he pulls through (he seems to act as normal and feeds well) is there any chance of him regenerating a new tail??
