Hello! I have a biocube 29 with 2 clowns, 1 green chromis and a firefish. Firefish was added just over a month ago and has his cave well established. He is doing great. Eating and coming out from time to time. I would like to add a blenny. From what I have read I feel the tailspot would be a good candidate because of its reported peaceful disposition and smaller size. The only reservation I have is its compatibility with the firefish. There are a few other caves and plenty of live rock for the blenny to claim his own territory, but being a small tank I'm still unsure. Anybody have any experience with these two fish in a similar size tank? I'm hopping that because the firefish was added first and has his territory that it will be fine. I have been known to be wrong though
