A fellow teacher called me to her room today to ask for assistance. She wanted me to identify something swimming in her fish tank. She set up a small (1-2 gallon) fish tank in her room and prepared it for fish, but before she could add fish something appeared. They look like mosquito larvae to me and they certainly swim like them, twisting and wriggling to the surface. As a child I was very curious, so one summer I raised a few mosquitoes until they hatched. She only had three in her tank and I was happy to remove them for her. I placed two on a slide for further viewing. We’re both wondering when a mosquito visited her tank.
