So my blenny is up for sale or trade. I thought I would offer it on the forums before taking it to the store. Not sure how much adults are worth since I can’t find any local or online for sale. He is between 8-9 1/2" long and healthy. These guys love to burrow under the rocks so be forewarned. I have him in a secondary tank I would like to take down and make a frag tank possibly. I can try to get pictures but he usually just hides.
