I have a 29g display tank that turns 1 year old in May and has a medium sized hair algae problem. After some research I found out that lawnmower, tail spot, starry, etc. blennies are perfect for my situation. Now here is my question, I have 1x Yellow Watchman Goby, 1x Carmel Clown, and 3x Green Chromis; I understand that they are peaceful to all tank inhabitants unless they are of the same species and/or a fish that looks similar to them, and I really don't want my YWG to get beaten up or worse turn out dead because of this guy. So, should I get one or should I take the hair algae problem a different way?
