not sure of the species, but they are native to NJ whatever they are, the ones I used to catch when I was younger were much bigger. Tree frogs sound cool.
I was thinking that the leaves were a good enough surface for them to jump on they cover the water line. The water depth is only around seven inches, theres about 5" btwn the water level and the screen but I can add something else as well. I wasn't sure about the heater I do run the air conditioning at night so thats why I put an old one in, the filter will help keep the water clean and the smell to a minimum, I have it turned to keep the flow down to a minimum.
As of last night three more started on the first legs and the guy pictured above with the one leg now has two, he's the biggest and most active. Not sure if they are all from the same batch/clutch of eggs some are considerably smaller. I have given them blood worms which they seem to like.
Will make sure to update thread with growth pics. None of my fish are as active as these guys with the lights on..... unless its feeding time, so I'm enjoying them and my son is learning about the metamorporhisis process and trilled to see the progress of it daily.
