Hey, I've kept T.natans for around 4 years now but have come to a dilemma.... I recently moved and limited my colony down to two. The problem now is, now I cant quite seem to remember which sex is which. Heres 2 pics of the remaining 2 of my colony, can anyone please remind me which ones male and which is female? Both are equal in size atm and are virgins.
Female?
Male?
Female?
Male?
