They are terrific! I keep a group of five (one male, four females) and they lay eggs constantly. So much even, that I have to leave clutches in the tank because I have all of my breeding capacity full of little bicolors. Every day there is calling activity, sometimes more a day. Males make a loud canary-like sound, and a sort of 'burp' sound when stroked by the females.
When they're young they really eat a lot! If they don't get enough (good quality) food when young they can develop growing problems so make sure to feed them well, keep them in fruit flies all the time and give them a variety of food. The will grow really fast when their requirements are met.
The adults like larger prey items, like crickets, fire brats and waxmoths and their larvae.
My group started reproducing at approximately 11 months old. I've been in bicolor tads since...
Again, great species, love em!
