By April 2013 we will be putting tilapia fish into our aquaponics tanks. Right now the water temperature is 50 degrees F. Tilapia need 70 degrees or more to thrive.Until then, there are three little gold fish swimming around. These little fellows were added to the water in the fall as pet store purchased feeder fish, 25 cents a piece. On introduction they were skinny and sickly, barely surviving. In fact 70% of the fish didn’t make it.Now these remaining three are thriving and are 4 times the size. In fact the other day, I decided to plop a few small slugs (they are overrunning the place) into the fish tank. To my surprise the fish eat the slugs! Now we no longer have a slug problem, we have a fish deficiency.
