The 4 leucs were our first frogs. We just recently had our first clutch of 4 eggs. I am pretty sure I have 3 males 1 female, I try to tell them apart by the dots on their heads, but I forget if I saw 1 of the potential boys calling or not (both have 2 small dots and one large.) We also have 2 red eyes and 2 Azureus which we purchased at Frog Day. The tank homes our Leucs and was our first build. We tried a fancy background for our red eyes but like the tanks better without it; so much easier to maintain.
