My wife and I have been doing FOWLR
set ups for a while now. Never aggressive though. But can a lawnmower blenny survive with an Eel, Picasso trigger, Niger trigger and a Harlequin Tuskfish? I know it sounds weird but I like that blenny in all my other tanks because it eats hair algae. Which was a wonderful feature of that odd little guy. Thanks guys for any advice you have.
