We were going to separate them once treatment started to keep samples separate, left in normal tank for now to reduce stress, but I guess we could separate them now, at least that way they will get used to it. Plus it gives me a chance to get started on taking apart their viv and getting it cleaned and putting all the new stuff we've bought for it in.

Little one does eat quite well as long as he is fed before bigger one gets up or not near him, but it seems if the bigger one is up and near him he just waits and waits and then the food is spotted by biger one and eaten.
