i bought two bubble tip anemones for my pair of clownfish. my clownfish was a wild caught true percula female, and tank raised ocellaris male.
As soon as the bubble tip anemone opened, my wild caught female went straight in, under 1 hour.
The tank raised ocellaris didnt know what to do for the 2 weeks i had them, then i did a redo of my rocks and i must of scared my ocellaris and he went into the anemone.
i guess he figured it wouldnt hurt him as since that day he is hosting and loves it.
here is a video that i took today of my clowns.
