Two weeks ago or so, I got three n. viridescens louisianensis adults from a pond near my house. They've been doing great so far, but when I found them, the males amplexused the female quite a bit. I never saw a spermatophore dropped, and was wondering if there's any way to tell if she's been fertilized. They've left her alone since then. Also, how long after fertilization do they lay their eggs? I've got two large plastic plants with four live ones in a 30 gallon tank, about 8 inches full of water. I've only been able to find one female so far, and only kept 2 of the males. I'm pretty sure she's gravid, she looks fairly fat. Any information would be appreciated, thanks.
