Very nice. I had one hatch in the tank a year or so ago. It never grew despite the supplimenting and plenty of food offered. At 5 months old it was only about twice the size it was when it hatched. It eventually died.
I have given up on that species for now. From my experiences with them (and from what I heard from others who kept them), they dont do well with warm temps and it would seem like you would need to have the temps in the lower 60's (or possibly cooler) - which is a tough thing to do in the summer and doesnt really jive with what the rest of my pygmies needed.
I think the longest I kept any of them (WC) was around 6-8 months. IMO, its a species best left in the wild.
