Hello Everyone! So, I didn't realize how much I loved blennies. There's such a variety of them, like some that each algae and rock hop, some that act somewhat like jawfish by creating burrows. Such a variety and I can just imagine a whole tank with blennies, some of their heads poking out, some just swimming like an eel, etc. The only problem here is that from what I learnt, blennies hate each other. I have no idea why, I don't know if its food or just they don't like the shape of eachother but is there a way to keep multiple blennies in a single aquarium?
