Looking for new frog/frogs

[Dace]

I'll bet that if you had a 75 lying around for the 1 frog instead of a 20 high the absolute minimum would magically become 75... Seriously though what other signs? Has anyone actually experienced them fist hand? What brought about this sudden change in gray's housing requirements... I mean you can argue all you want but the frogs don't care anymore now than they did before...
