my brother picked up a neon green bubble tip anemone about a week ago. anyways its really large, today it was shrivilied up and so small. i couldnt believe it was the same one. anyways later on it stayed that way and it was large again. well i take a look later on and its oozing out some brown stuff, from me reading on the net its how they use the bathroom lol. anyways it stayed small and to me personally i dont know much about them but i think its dying. he feeds it and it eats fine me or him dont understand whats going on.
as of now the anemone is huge and thriving again.
it looks great right now.
is this a way a anemone behaves? if it was dying i dont think it would be all huge and open like it normally is.
does anyone have a general idea on this or is this just how they act normally
thanks

This is pretty normal anemone behavior. They are mostly water and inflating and deflating is how they cleanse themselves. And yes, the brown stuff was poo.

great, thanks for the reply. its good to know that its ok.
he bought some kent marine coral vite and just started adding that for the anemone and his corals.

I feed my corals a variety of foods. I am not really familiar with the Coral Vite but Kent makes good products.
