A bit more difficult to sex leucs. Here I thought I had 3 females in a 4 leuc tank and it turned out 2.2. I also did move 1 female in another enclosure and she passed. I had a total of 5 of them for over 2 years in the same enclosure. I still have the 2:2 ratio, but in 2 separate tanks. Hope you have the 1:1 leucs too. Nice viv!!
