Aww! How tiny!! Adorable

I kept my leucs on sphagnum.. and although paper towels are recommended.. I think that is mostly for the ease of picking up feces if you intend on sending it out to be tested. You may want to add some leaf litter in case they want to stand on something a bit dryer than moist moss.

Ha, it is an addictive hobby! I have plans of ending up with around 20ish tanks myself over time. Although it is tempting, you may want to wait to get more frogs until you have your azureus in their home and you can make sure that they are doing well. It is a big plus that you have someone close by to get frogs from. No one in my area has any darts.. so I have to have mine shipped. It adds to the stress of the frog and I wish I could find someone in my area to get away from that.

As far as the lid goes.. hmm. Maybe if you try lining the edge of the tub with paper towel? If you did that you would need to make sure that there were no gaps for your little ones to get through. I've never tried it.. so I can't say if it would work or not.. sorry.

Once again, congrats on them! They are beauties!
