"HELP" Rapid tapping noise freaking fish out

[Leah]

I had a mantis and new where he lived and I took out the rock and poured top off water
in the hole and out he came into a bucket. Easy if you know exactly where he is hiding.
I am just leaving it and not getting to excited about it. I really doubt you want to be doing the dipping on all your rock a trap might be better in that case.
