May be a strange question, but do FBT sleep?

[tearsmith]

My two fire belly toads like to rest on their rock islands or under a little rock cave. Thing is, they never close their pupils all the way no matter whether light is on or not. I work days and nights on a rotating shift so I have been home at all hours to check it out. How can I tell if they are asleep? Do they sleep or just rest?

Also, my fire bellies eat mini feeder guppies, meal worms, and gut loaded crickets. I feed the crickets carrots to enhance the toads belly color to the true red they are in the wild. Is there any other natural food I can give them that will enhance their color?

They usually sleep with their eyes open, or only partially closed. You can't really tell they're sleeping just by looking.

As for the carrots, I don't think they're going to help very much with the red coloration. I suggest you dust crickets with something like Repashy Superpig, which has lots of natural color enhancing additives - it really works.
