Mine are in two groups and they now reside in the garden. Despite them both having mesh lids I am frequently having to oust frog invaders of various sizes.
A few weeks ago I fished them all out to check their sizes and body conditions. They are all growing again and looking well.
Despite them now being a little over a year old, their is no enlarged cloaca ..they all look the same
Body shape wise though I would think I have both sexes. I had read that these could all well turn out being female. I did save a link that suggested that this would be most likely, but I am clueless as to where I saved it.
I will fish them out again soon and will take some more photo's.
