Hey Cam, I'm glad that you've gotten into the hobby! It can be very fun and a little less lonely once you have all your new froggie friends.

I do have to ask though, are you housing your Green Tree Frog and your Red Eyes in the same tank with a house Gecko? I ask this because as a general rule of thumb we in the hobby try to avoid housing different species of frogs together in the same tank. The same goes for your gecko, lizards can sometimes be the natural enemies of frogs and I don't think it's very healthy for all of them to be housed together. All different species of frogs have different toxins in their skins that can be harmful to other frogs if they're exposed for too long. I highly recommend that you separate them immediately and put the house gecko and Green Tree Frog in a different tank. Also generally even if the frogs are the same species it's best to separate any newcomers you buy for at least 30 days to make sure they're not caring any parasites or diseases that could effect the health of your other animals. This goes especially for wild caught animals, as they are often born with parasites that will become hostile once they are captured and put into an enclosed environment.

These are just my recommendations. I hope you find them and any other information you seek very helpful.
