That's exactly what I use for my hatchlings/juveniles. My adults however get larger ones because their tubs are larger, and I need more humidity. I'm guessing you'll need larger ones for the same reason. Plus those little ceramic dishes get knocked over by the adults, they just aren't heavy enough. I use $1 dog bowls from the dollar store, they are plastic and easy to clean. Just make sure you get a style that can't tip. The dog bowls I use are the kind the expand towards the bottom. You can find the exact same bowl at Walmart for just over a dollar. It's black/blue/silver with dog bones on it. It works perfectly for me.
