So well here is my set up.
Looking down. I still am going to tinker with the top. I might make an all clear mesh lid because then I can make a feeding door for each side. though the plastic helps keep head in... idk
This is Jasper's side.
They really don't flare or try to get at each other. Though Kristoph did flare a few times his calmed down. I think now that he has more room and there is a filter his happier. And I haven't noticed any new tail damage since I've put him on a sleeping schedual. YAY!
Jasper is super mellow, and tiny. He hasn't really been eating but everyday is a little bit more and more. I think his going to enjoy his new home greatly.
