Agree on all of the Above 100%noki said:1. is a Red Top Zebra type. Might be Metriaclima greshakei, which is more common. Not a Perlmutt at all.
2. juvenile C. Moorii Hap
3. young Metriaclima callainos "Cobalt Zebra"
4. Yellow Peacock. Close to a Baenschi but may not be exactly. Looks like a decent male.
