Ecosystem?

[BettaPonic]

Would something like this https://www.amazon.com/dp/B01FRX9DW0?psc=1 on the back of a ten gallon with Least Killifish in the tank and the thing on the back. I would like to be able to raise food for Guppies, Least Killifish, and Betta.

What kind of food are you thinking of wanting to raise?

I raise Vinegar Eels in a 16 oz water bottle and quart. In the dark of the cabinet. and there are zillions of them, lol .

What is a vinegar eel? I raise grindal worms and they are easy and the fish gobble them up.

I also raise Vinegar worms, but I cannot raise those in the tank.

Yes, that is true they cannot be grown in the tank - they need the vinegar.

Here is the info, they are so tiny I can barely see them, use a slice of apple and Braggs apple cider vinegar in the jar.

The hang on the back or fuge type things return water back into the tank, so I can not think of a worm or creature type food to raise in the back. Other than maybe common Cherry shrimp.

Which you would need so many to actually feed the fish. Breeding in that small of a space wouldn't be able to produce enough babies for daily feedings.
