hitch hiker

I bought some zoas and mushrooms recently and they came with some hitch hikers. I was just wondering what they were and if they are good or bad? Thanks Carl

Hello Aiptasia!!!!

aiptasia is bad...get a peppermint shrimp and he will clean it up for you.

The first one looks like hair algea, which is a problem algea. You could probably just rip it out with your hand. The second one is definitely aptasia, a problem anemone. It looks somewhat big from the pic so I don't know if a peppermint shrimp will eat it, they usually go for ones that are smaller than a few centimeters in diameter. If the rock can be pulled out easily you can do a quick dip in RO water or try and scrape it off with a knife (assuming it doesn't receded into a hole, which they sometimes do). A very successful way to get rid of it is by squirting boiling water at it, that will melt it away never to return.

First One actually looks more like blade caluerpa there is a debate on this one whether good or bad,, and the second one is definately an Aiptasia anemone. BAD
