Has anyone used live food to feed their tilapia? Today I fed some fly maggots- I think they were black soldier fly maggots to the first fish that I just got yesterday. This was their first meal in my system. I couldn't tell if they ate the maggots as my IBC was a bit cloudy and the fish were hiding in a plastic pot at the bottom. Not having to buy fish food would be very sustainable.
Here's a link of a commercial maggot factory. There are also DIY models that some youtube uploads show.
I plan to build one when I get the time. Have anyone built and use one. If so what are the advantages and disadvantages that you have found.
