Hi Happy Frog,
I currently have 3 very small broms in my imitator enclosure. ( brom species -unknown)
I worry about the water, actually.
I have re-positioned the 'tilt' on them a few times.
I have spoken to breeders that have stated they have lost new hatched tads because they 'drowned'.
(If left in the main tank, of course)

I can see how this could happen. Even an adult will ,really, push themselves down inside.

ie :Last night in the imitator enclosure: My male spent hours calling ( they have been busy as of late ). He was in a brom ( facing out). The female positioned herself right in front of him. He was very covered with water. If the brom was positioned vertically ........the water would have been much deeper then he is long.

Plus, I often wonder why we even use them ? since most darts live on the ground, close to the ground, or in trees close to the ground; and most broms are terrestrial. Having said that, I'm sure there must be some small species of brom that grows on/or near the forest floor among the leaf litter and debris? I would love to know what species species is. We can't plant pineapples

There are a few plants that have cupped leaves that water will sit in if you have a regular misting system. There is one, in particular.....of course I have forgotten the name of it. I will take a photo if this plant and post it here later. It does very well with constant 'wet feet'.

Just food for thought.
