Digital Tank-Side Feeder
A flat hopper that hangs inside the rim.
It hooks over the glass and sits inside the tank rather than perched on top, which is the answer for a hooded tank or one in a cabinet with no headroom.
Taxes calculated at checkout
- Hooks over the glass instead of clamping on top
- Flat enough to sit under most hoods
- Touch panel sets one to four feeds a day
- Takes flakes, pellets, powder and strips
- Also suits turtles, newts and frogs
Why you'll love it
Made for happy, healthy pets
Most feeders assume an open-top tank
Drum feeders need headroom above the rim, which a hood does not give them. This one hangs down inside the glass, so the lid still closes and the light still sits flat.
A wide hopper does not bridge
Narrow chutes arch over and stop dispensing, usually on day three of a holiday. The flat tray here is wider than any pellet is long, which is the whole reason it keeps running.
One feeder for the whole shelf
If you keep a turtle or an axolotl alongside the tank, the same unit handles them. Amphibian keepers otherwise end up buying twice because most feeders are sold fish-only.
Good fit if
- Fully hooded tanks with no clear space on the lid
- Tanks in cabinets where height above the hood is limited
- Turtle, newt and frog setups as well as fish
- Anyone whose clamp-on feeder will not fit
Look elsewhere if
- You have plenty of clearance and prefer a larger drum
- Your tank has a bowed front, which the bracket may not grip
- You need more than four feeds a day
The clearance problem
Most automatic feeders are a drum on a clamp, and they need vertical space above the tank to work. A fully hooded aquarium, or one sitting in a cabinet with a shelf above it, frequently has nowhere for that, and the feeder either does not fit or has to be balanced somewhere it will eventually fall.
A flat hopper on a hook bracket solves it by working inside the rim instead of above it. The body sits against the glass under the hood, so the only requirement is a gap at the rim to hook over, which almost every tank has somewhere along its length.
Trade-offs against a drum
The capacity is the same five hundred millilitres, so there is no compromise there. What you give up is distance from the water. Sitting inside the tank means the hopper is closer to the humid air rising off the surface, and moisture is the main cause of a feeder clogging.
That makes food choice more important than it would be with a drum mounted higher. Pellets tolerate damp far better than flake, and it is worth switching to pellet before a long absence rather than discovering the hopper has set solid halfway through a fortnight away.
Setting it up
One to four feeds on a twenty-four hour cycle covers everything a community tank needs. Two smaller feeds usually suit small fish with fast metabolisms better than one large one, and it also means a single misfire is less consequential than it would be with one feed a day.
The touch panel is straightforward, but check the setting has actually taken by watching a full cycle rather than assuming. Then run it for several days while you are still at home. That is long enough to confirm the portion, the timing and that nothing has clogged, and it is the step people skip.

Keeping it dry
Empty and dry the hopper between trips rather than leaving food in it indefinitely. Wipe the inside with a dry cloth, and check the outlet specifically, since a plug forms there first and is not visible from the top of a full hopper.
Take the unit off the glass occasionally and dry the bracket and the back of the housing. Condensation collects where the body meets cold glass, and that is where corrosion starts on the contacts if the unit is left in place for months without inspection.
Good questions
Before you buy
Shape, mostly. The drum holds the same 500 ml but stands above the rim and runs two months on a charge. This one is flat and hangs inside the glass, which is what you want if the tank has a hood.
It runs on batteries, so there is no cable into the tank. Change them before a long trip rather than after, since there is no low-battery warning worth relying on.
The bracket needs a flat vertical section of rim to hook over. On a bowed front, mount it on the back or side glass where the panel is still flat.
It hooks over the glass and sits inside the rim rather than clamping on top, so it fits under a hood. Capacity is the same; the trade-off is being closer to humid air, so it clogs more readily with flake.
No, it runs on its own power rather than mains. Check the charge or the cells before any trip rather than relying on the indicator.
The bracket needs a straight section of rim to grip. Most bowed-front tanks have straight sides, so hook it there rather than on the curved front panel.
