I have Flag fish and Least Killies in an outdoor tank. They are all more active and breed more in the summer months. When the water temp drops into the low 40s during our So Cal winters the numbers go down and the Least Killies don't get as big.
I kept wild caught Mosquito fish in another tank for a while but they were skittish and not happy in the tank.
