So on Monday I came to work to find my six line laying ontop of the filter pad in the middle chamber of my biocide. I thought it wasdead but when I went to pick it up it started to flap around. There was waterflowing over the top of him so I guess this kept him alive. So I put it backinto the tank and it took cover behind the rock work. I saw it a couple oftimes this week and today. Well I noticed that it has lost its entire tailfine. I don’t know if something has been picking at it but it’s gone. He stillswims around but stays behind the rock work where I can’t get to him. I’mconcerned that he is going to die. He looks ok except for the tail. Can theylive without their tail fin? The tanks only a 14 gallon biocide with him, aclown, bi color blenny and a yeti goby and pistol shrimp pair. Please anyadvice will be helpful. Here is a pick of his tail.
