Maybe raising fish in swimming pools will become a fad some day. I been thinking of raising mosquito fish inside my filters to keep bugs from laying eggs in them. The trick is, how do I keep the mosquito fish inside the filters so they don't get eaten by the tilapia. I wish I had bought a bunch of twelve dollar kiddie pools before the stores all sold out of them. Now I can't buy them at any price. I suspect the same thing will be happening soon with the bigger pools online.
