Well, your main problem might be that your not letting them feed as they wish now, don't schedule their feeding times anymore, just drop in 10-20 crickets every 2nd or 3rd day, and they will hunt for their food. Mine are the same way now, a lot less "tame" and they won't eat unless in their vivarium.

I give them 15 crickets every 3rd day, and they are fine. Bruce, my black toad, looked a little skinny (wouldn't eat anything for a while) about 2 weeks ago, so I took him out of his viv, put him in a 5 gallon quarantine tank with one hiding place, a water bowl, and the rest was open, and for one week fed him five crickets a night. Within that one week, he was back to normal, my problem is, that in their current viv, the crickets have a lot of places to hide, but that encourages the toads to hunt in a more "naturalistic" emviroment.

I'd be worried if they didn't come up for 3 days. They may be comming up at night, hunting for pill bugs, then returning to their hole in the morning, my one toad does tis all the time, been in the same hiding place for 2 weeks, but turn on the light at 3:00am, and there he is, out hunting. My chubby frogs have holes all over their viv, and when they go back into one, it looks the same as if they hadn't even come out of it.

Our babies are growing up, it's just life.
