Firebelly Toad activity decrease?

[MollyDayBonnie]

Newbie here, with the inevitable newbie questions ...

Two weeks ago I brought home 2 FBTs for my 10-gal planted vivarium (details of the habitat are given below). For the first several days the toads were really active; the male called in the evening, I saw one catch a cricket after lights out, and they both hopped all over the vivarium.

However, after those first few days, the toads started hiding behind the waterfall. They have not come out at all in the last several days. They are still kicking -- the male calls constantly, day and night, and when I peeked in on them this morning they were still both bright green and wriggly.

1) Should I be worried about this change in their behavior?
2) Should I be worried that I haven't actually *seen* them eat since those first few days? I keep adding crickets, and don't seem them after a day or so, but I'm worried that they are just finding hiding spots in the planted tank. I even tried waxworms (although I know they should not be fed regularly) yesterday; I left them all day and overnight in a jar lid, but the little green guys just weren't interested.

Set-up:
10-gal divided tank with a secure screen lid. Daylight-spectrum fluorescent bulbs in a partial hood on top, with a piece of glass for controlling the humidity. The tank is split 50/50 between water and land by a plexiglass divider I installed.

The water portion is 6-in deep, with lots of spots for the frogs to haul out on, and easy access to the land portion at all points along the divider. A small filter also runs a waterfall. The water temp remains at 70F, and I do regular 25% water changes with room-temp dechlorinated water. I'm an experienced aquarium keeper, and am sure water quality is not an issue. The frogs share the water portion with 4 small guppies (no problems there, thus far).

The substrate on the terrestrial portion is a mix of coco fiber, orchid bark and leaf litter over a layer of river pebbles for drainage. The substrate is planted with a variety of living mosses and one small tropical plant with leaves stiff enough to support the frogs. A small flowerpot sunk in the substrate (and covered with moss) provides a hiding spot. The background is oak bark I collected and sterilized myself.

The temp remains between 72-74F during the day, and falls to 68F at night, while the humidity remains between 70-80%.

I've been feeding small-sized crickets (14 days), gut-loaded and dusted. As I mentioned, I also tried waxworms, with no luck.

I'd appreciate any feedback that anyone can give me.

I think you will be fine as long as they are healthy looking. just watch for signs of malnutrition.

Thanks for the reassurance. Things are actually looking up; one of the toads came out yesterday and ate several crickets. I also added a 1/2 log in the hopes that with more hiding spots available they would abandon the waterfall. No luck yet, but at least I know they aren't on a general hunger strike!

Can you get some pics? we mite be able to give suggestions if we could see the tank.

My camera is currently defunct, but I'll see what I can do.
