Thanks for the replies you guys, I'll throw some pics up asap... its like 2 in the morning right now so it's pretty dark..lol
I've been feeding them moths, flies and mosquitoes. I'll probly pick up some fruit flies like you mentioned as well. Thanks.
I threw in a large fly today (almost the size of the frog itself), just to see if they'd go for it, and the biggest one did.... although it took him a good few minutes to swollow.
I doubt it was a good idea because i don't wanna over feed the little guys... but he seems to be happy lol, and it's not like i'm forcing it.. what's you're opinion on over eating? Can it be dangerous?
