Wrasse in overflow....again

[sslak]

I want to see a mesh catapult that launches the fish back into the tank when they land in the overflow. You could power it with like a mouse-trap sort of contraption. Hahah.

you build a catapult, and there will be some whacko fish that actually learns to do it on purpose cause it's fun. THAT would be something to show house guests!

Plastic gutter guard zip tied to the teeth of the overflow to keep them out. For a lid I used a window screen frame the size of the openings in my tank and instead of screen I bought plastic mesh 1/4" pond netting. Plenty of air exchange, keeps the critters in and doesn't block any light.
