Fish Traps

[Oscar]

If partially buried in the sustrate will the pop bottle trick work for capturing crabs?

[Stones]

If its crabs you want out of your tank, instead of using a pop bottle, just submerge a small drinking glass or a large shot glass into the substrate at an angle. Put some type of heavier bait in like a large piece of shrimp and leave it overnight. Crabs will crawl in to eat the shrimp but not be able to climb up the slick glass walls. If the crabs are small enough, the plastic tubes superglue comes in work pretty good.

Excellent, now where did I put that shot glass?

Just don't use a shot glass with red screen printing. The salt water reacts with the printing, ruins the shot glass and gives you lots to clean up.
