You can check what your female is by looking at her rays. Just because she spreads 180, doesn't prove she's HM. If her rays branch out more than twice, she's delta/HM. If its spreads 180 AND has 3 or 4 sets of branching, she's HM. If it stops at two, she's VT.
That's the hardest part of females, telling what their true tail type is!
Adorable fry, too!
