I would add fish but the pan and barrel are on a slant and the backside barely has enough water to keep the prepupas in. The pan is pretty shallow.
The prepupas don't seem to know how to swim. I seems that when they hit the water they're in shock until they're removed and then they come alive! It only takes them a split second to start climbing up the straight sided container.
I only deal with the dark ones (prepupa stage). I still have an aversion to touching the larvae. I pick up the prepups by hand only if I have too but I still love them. I am getting better though.
