well really just keep adding zoe to its food, mine split many many times..... right now its just looking for a good place to settle in, it will move less often after that...
splitting is cool and we use it as a way for "trade bate" with our LFS... Too many will cause alot of waste so you'll se an increase in nitrates.. but you should do it tho just to experience it, its kinda wild how it does it....
ZOE ZOE ZOE ZOE ZOE in every feeding and that baby will split in time

feed it often, a few times a week if you want it to split.... honestly, mine gets fed mysis with zoe only...
glad to hear all is well with you anenomie....
