it is defintely interesting - I plan on doing the same in the future - just to look at the size of my male borealis and my albino female laevis - the scale difference is so funny, the idea of him amplexing her is enough to make me laugh!

I will probably have more luck with a male laevis to a female borealis due to size.

I also have a runt laevis - full grown male at 2.5 inches. I may mate him with the borealis female because their sizes work perfectly - - hmm. maybe some future experiment!
