Our large male Rotkiel has been showing odd behavior for quite some time now. He was in with a group of Daemons and he began to lean over to one side when the Daemon came near him and they started to suck his side and as they were removing slime coat we decided to move the Daemon. He has now started to do this to all the other fish in the tank especially the wavrini which we put in to replace the Daemon.
Apart from that problem we have another concern about him. He was part of a breeding pair but for a long time now he has been very rough on the female to the extent that we have now removed her from the tank. The last time she spawned he only managed to fertilize a few eggs and on close observation his vent seems to be gaping open quite a bit. The entrance to the hole is about 3mm and tapering in to a point 2mm deep. Any ideas. Pic below is the best I could get
