Planaria Trap Tips and tricks? The answer is, YES they absolutely do work. You load up the planaria trap with fish food and wait patiently for the planaria to fill the container. Now, I've been told to leave the trap in the tank, in my experience this is a bad idea as they all end up climbing out of the trap over night. Now for the tip as to what food to use, planaria THRIVE on eating shrimp, so in that case, I fill the traps with shrimp wafers, brine shrimp, etc. This is how I have always kept this 55 gallon as free of planaria as i possibly can. Especially with my large amount of shrimp reproduction. Me personally, I cannot stand the planaria. Another tip to handling planaria is having fish that will eat them, but wont eat the shrimp. This is the complicated part, hence why I'm using a 55 gallon so the shrimp can spread out and my corydoras won't be able to eat them all.
