Im not sure if this is in the right spot but please let me know if it isn't.
I have a green long tentacle anemone that seems go get bigger for a few minutes then gets shrunken to where it looks like a purple ball ( odd I know ), my question is as to when it enlarges itself, does that hurt it or is it normal for anemones to get really big ( during daylight ) and shrink to basically a ball ( night time schedule ).
Also on that note, do clownfish( tank bred occerlarus ) that host it normally prevent you from feeding the anemone krill/silversides/prawn heads?.
