Cooper eats like a pig, and doesn't eat aiptasia.......
Funny thing is I bought four peppermint shrimp as well, and put them in a critter keeper with some aiptasia rock and they just mowed it down, in fact we think they grew overnight.... :? 8)
He's in the 45g "aiptasia tank" for now Alan. He seems a lot like Spike, very friendly.
Except he hasn't gone for the polyps on the colt coral in there......Spike for sure would have. (Spike is a blackback butterflyfish for those who don't know him).
I'm thinking he'll end up in the 155g at some point soon. It's a lot more peaceful in there now that the clown tang moved to Dez's.
