I think thats the toadstool youre talkin about thats twisted.... It was poutin cause a hermit crab beds in it and irritates it. I had to knock him off just to give the toad some peace
Thats a bi-color blenny. They are the funniest fish I have owned yet. When I got the Achillies, he followed that thing all over the tank and would peek out at him but run into one of his many hiding holes when it came his way. That achillies didnt give two flips about him, but to see that blenny act, you would think the world was all about him and that he was somehow being chased by that achillies.....They are funny as heck
