I have had my FBTs for a few days now and they are quite active and healthy. However, my concern is my set up isn't great for them.
I keep the appropriate humidity and temperature levels, have cocofiber substrate, and even some moss to keep the area moist. Though I have seen many people with more of a half land half water set up, where as I have a very large soaking dish. All three of them fit with more than enough room and I do daily water changes with water treated with seachem prime.

Though off topic, I love these little guys. They are a joy to watch
