Hi y’all. I’ve had this bicolor blenny for well over a month and about two weeks ago I noticed him coming down from his rock and kicking up sand in the same exact spot every single time. Note i’ve never seen him flash on the rocks. It almost seems as if he’s just kicking up sand with his tail? I’ve gone through two treatments of prazipro and he continues to flash on the sand. He’s been eating fine throughout this whole thing and has no visible signs like spots or anything. I keep two clowns with him and they show no signs, they don’t flash or anything which leaves me confused. Help would be very much appreciated, thank you for taking the time out of your day to help me.
