So I got this green bubble tip anemone about 5 days ago, it is the second one I've had. After my tank crashed and i lost most of my livestock and my first anemone I gave it almost a year before getting this one. So for the past 3 months my parameters have been perfect and ideal for anemones so I saw this one and it didn't look magnificent when I got it, looked kinda stressed. After 8 hours of being in my tank this anemone blew up with color and bubbles literally looks super healthy. So made me more confident in my decision to give him a home( because the customer before me in line bought 2 oscellaris clowns and a condy anemone... which their tank is new and they probably just watched Finding Nemo cause Dori is coming out soon... and the husband pretty much told me off when I questioned them, so I'm sure that tank has crashed by now.) T\My Anemone, Luna as my wife named it looks great only moved half an inch from where I thought would be a great place and hasnt move in 5 days. I fed it 36 hours after it was in my tank cause I'm not sure if they feed theirs. Either way my wife and I are concerned cause its mouth is slightly open like the size of half a pea, and people tell me they should be tightly closed. Is this normal or should I be concerned. After I fed the anemone it took it in less than 2 seconds and that piece of shrimp was gone. Afterwards its mouth look kinda inverted then quickly with back to normal. and last night and today its mouth has been like i said open the size of half a pea.
