Thanks for the great suggestions.
Maybe I just don't get the genetics.

Why is it, that Hypo X Hypo = 75% hypo 25% normal ?

Shouldn't Hypo X Hypo = 100% hypo ?

I would love to replace the hypos and anerys with DH/TH. However, getting me this far, has exhausted all the play money. Plus I still need to buy the permanent housing (med/lg vision cages).
