Our 2 toads are getting settled in to their new home for several weeks now. They seem
to be happy.

I have about 60/40 water/land with about 2-3 inches of water with several islands, etc.
I have a mini filter which does a great job keeping it clean. I placed the filter under
several flat rocks. So the filter is hidden and keeps the water flow down.

However the toads decided that getting under the rocks inside with the filter is a neat
hidding spot. They have other rocks and plants in the water and land which can be
used for hiding.

We a little concern on them hiding with this filter.

Any ideas on why they do this?
