Thanks for all the replies guys. Its difficult to know when the little one has had too much. his fins are torn, he is still able to get away from the big one, but there was an attack, every 3 minutes or so, so i separated them for the 3rd time. I am going to give the little one a rest, he is just in the sump. I got a Caribbean anemone today, lets see if the big one shows any interest. @
hdsoftail1065 How bad was the little lightning in your situation? was its fins torn? May I just shouldn't watch, but my little one, just didn't submit. Maybe its an idea to put them in a small container and hope the wee one does the submission move.
