I bought this Smith's Blenny here and to show you how hardy this guy is, he was the most active of 5 fish I had delivered when outside temp in MN was 21 degree out and bag water was at 68 degrees. All survived after 2 1/2 hr slow drip acclimation. He is a colorful little guy to watch darting around the tank. He is constantly on the move searching for food or detritus on the bottom as well as on reef rock. Likes to dart in and out of rock. He is getting much better at snagging Mysis shrimp I drop in before the other 6 fish hog it all, especially my Hamlet Indigo who gobbles everything that moves. A joy to watch.
