Im about had it. Everyday i wake up and find something new. Hopefully this is a good thing to have. Im battling hydroids. Little light...no feedings...kill em when i see them. My beautiful zoas are still struggling to thrive. Picking up some peppermint shrimp this week to eat them. Now hair algae. Going to be cleaning and scrubbing rocks today for that. But now i just woke up to find this bugger. Does this ever end?? Please tell me its a good thing to have.
