This is really embarrassing. Even though every post I read regarding false bottom tanks recommended
blocking or capping the fill tube when not in use, I put it off as "something to do later". Well, guess what?
I now have an aqua cricket.
Hopefully, the photos below will motivate everyone to cap your fill tubes

Aqua cricket breathing under water (not).
After capping, the fill tube is still an attractive nuisance. The fake plant is a feeble attempt to hide the fill tube,
but all it really does is provide a stairway to cricket heaven. The tank is home to a sub-adult emperor that apparently
is not very hungry right now.
I'm not really happy with the current cap, but it's all I had available. I may need to find a good old fashioned
cork or perhaps the right sized marble.
