Merry Christmas everyone, and I know it's Christmas Day, but something odd happened to o e of my FBT's today.
I don't know if it matters, but yesterday I moved them into a new, bigger setup but used all the same stuff apart from new Eco earth and moss - though still the same as what was in their original setup.
Anyway, this morning I noticed one of them floating around and not really swimming properly and rubbing his head and eyes. Then he was sort of twitching and arching his back, getting his back legs and rubbing at his back. As I watched him for a minute or so, I noticed what looked like a kind of mucus covering him and restricting movement of his legs. He carried on twitching and rubbing for another minute, and seemed to rub whatever it was off him and get free of it.
Now he's swimming and climbing as normal. I can't see any lumps of mucus in the water or covering anything, don't know where it came from.
Do they secrete anything from their skin or something? The other 2 FBTs are fine, no problems.
