Ha ha yes I love my blenny he is such a lot of fun
well the rock and the hermit were both got off the cost of Sri Lanka when I went on vacation... Ah the perks of living near the ocean
yeah he is pretty big... The rock is doing great as a filtration media as I only have a small hang on back filter with bio beads and filter floss... Going to add another hang on back on the opposite side with filter floss and some activated carbon...
