My yoyos are doing great...i just realized that one has gotten considerably larger in the last week...and develiped a yellowish colour to his/her hand-like fins...its still healthy and as active as ever and Im wondering if this would indicate that its a male or female? The other one hasnt changed and is still growing at the normal rate. They play tag all the time but lately its been the larger one doing most of the chasing. Any thoughts?

Attatch a string and roll them up in it..then with one end of the string attatched to your finger let go of the yoyo. =D

idk... check

says something about redness around barbels and such. About as conclusive as the crap I searched up for my rams..
