Another fresh notion  :-)
Instead of having a side of the inner tank low as a spill way or
overflow, have a panel shorted on the bottom end to led things crawl
up.

What about suspending a short dry land tank inside but not at the
bottom of the big tank?  Under it you could have "caves" from a pile of
rocks, so to speak.
