I have a very large serpent star in my 155 .Normally he hides by day but right now I saw him out and about and saw to large half an inch rips in his round body . he seems to move around fine and is looking for food , but I am really worried . Earlier today I saw transparent gue floating in the tank and do not know if he is releasing any toxins . Has anybody seen this before and is he able to heal from such a large injury . ? And what could be the reason for it ? Could he have been stuck? I have seen a large shell ( 5 inches) out of place and he likes to hide in them? i would love to hear your input!!!!THANKS!!!
