Backyard Aquaponics
A place to discuss aquaponics

I'm sure I threw the paperwork away for this but here are some pictures. It is about the size of a base ball, a dispensing tube is inside that fills up as the feeder turns and can be adjusted a bit. It feeds twice a day. Aprox a teaspoon full max per feed.

Seems I'm getting old brain today as I can not post anymore pictures. Hope you get the idea anyway.

i was thinking of getting one of those for my aquarium, but the cheapest i could find was around $40 (and it didn't hold or dispense as much as i would like)

It has its limits for sure. gods $40.00? I like the concept though it would be nice to have one only a few sizes bigger, clip right to the tank and let it do the job. Worst think about having pets is having to feed em when you want some time off.

so true GF, yeah our aquarium trade is tiny compared to that in america. And so our prices are generally abit more. We (well South Aus) has the small local pet stores. As opposed to the big multi million dollar multi store companies my american friend said they have their.

(But china seems to be one up from America, with whole malls of just fish stores, and their feeder fish cost around 100 times the price to buy the same fish here)

Here is a feeder seems to be nice size? Online specs also.Smarthome

some info for you guys


Each fish rearing tank is supplied with a hanging demand feeder. A demand feeder is activated by the fish when hungry. It consists of a feed hopper having a hole on the bottom with a control plate and rod. The control plate is adjusted to the width of a feed pellet and keeps feed from pouring out of the hole. A rod connected inside the hopper and through the hole and the center of the control plate extends down and into the water. The feeder holds 50 lbs. of floating feed. When a fish is hungry it bumps the rod with its head and feed spills from the plate into the water. The fish can then eat. The fish learn to do this in about 3 days. The control plate can be adjusted to release feed easily during the training period. The manager can assist feeding by tapping the rod and releasing feed. Using demand feeders is a good practice. It reduces labor that would be needed if multiple feedings were scheduled throughout the day. Tilapia have a small stomach and long intestine and are better suited to eating many small meals rather than two or three large ones. Feed tables, growth rate charts and sampling are not needed. Finally, they do not overeat and feed conversion ratios are approximately the same for demand feeder and hand fed rearing.
