Why you'll love it
Made for happy, healthy pets
Capacity is what runs out first
A goldfish eats several times what a tetra does. A 175 ml drum is the difference between a feeder that covers a fortnight and one you refill on day four.
Two ways to mount it
The clamp handles a normal tank rim; the velcro strap handles everything else: a pond post, a hood with no lip, an odd-shaped edge. Most feeders give you one option and fail on unusual tanks.
Pellets are what it is built for
The wide outlet suits sinking and floating pellet, which is what larger fish are usually fed. Fine flake is better handled by a smaller feeder with a narrower gate.
Good fit if
- Goldfish, koi and other genuinely large eaters
- Ponds and edges with no rim for a conventional clamp
- Longer absences, where capacity is the limiting factor
- Pellet and granule feeding rather than flake
Look elsewhere if
- You keep small community fish, where this is oversized
- You want a wi-fi or app-controlled feeder
- You need very small precise portions
Capacity is the whole point
Standard feeders are sized for community tanks, where a small daily portion means a hopper lasts weeks. Goldfish and koi eat considerably more, and a small feeder emptied in four days is no use for a fortnight away regardless of how well it works.
Working out how long a fill lasts is straightforward and worth doing: load it, run it for a week at your normal setting, and see how far the level drops. That figure tells you what you can actually rely on, which the stated capacity on its own does not.
Mounting where there is no rim
Aquarium feeders assume a glass rim to clamp to. Pond edges, coping stones and open-topped containers offer nothing of the sort, which is why the velcro strap matters: it fastens around a post, a rail or a bracket where a clamp has nothing to grip.
For outdoor use, position matters more than in a tank. It needs to be sheltered from rain, since water reaching the drum will set the food solid, and out of direct sun, which cooks the food and shortens the life of the plastic. Under an overhang or inside a small housing is the usual answer.
Food types and portion
Pellet and granule are what this is built for, and they suit it well because they flow freely and tolerate damp far better than flake. The adjustable outlet sets the dose, so match it to what the fish clear in about two minutes and resist the temptation to be generous.
Two AA cells rather than a mains adapter is a practical advantage outdoors, since there is no cable to run to a pond and no plug standard to worry about. Carry spares and change them before any long absence rather than at the first sign of a slow drum.
Up to four feeds a day is more useful with large fish than it sounds. Goldfish and koi digest better on several modest meals than one heavy one, and spreading the same daily amount across three feeds puts noticeably less strain on the filter than dropping it all in at once.

Weather and cleaning
Empty the drum completely at the end of the season and dry it out. Pellet left in a damp feeder over winter turns into a solid plug and often ruins the mechanism, which is the most common way one of these fails outdoors.
Take the batteries out for storage, since a leaking cell over a winter destroys the contacts. Check the seal and the outlet before putting it back into service in spring, and run it for a few days on a test schedule before trusting it with an absence.
Good questions
Before you buy
It is not weather-sealed, so it needs to sit under a cover or inside a pond house. Rain into the drum turns the pellet to paste and jams it.
The manufacturer makes one and we have chosen not to stock it. It is an unbranded radio device with an unvetted app, and we would rather sell the version that just works offline.
For a few goldfish on two feeds a day, comfortably a couple of weeks. Fill it and count the days once at home so you know your own number before a trip.
Yes, with the velcro strap for edges that have no lip. Shelter it from rain and direct sun, since water in the drum sets the food solid and heat degrades both food and plastic.
Not this one. It runs on its own timer with two AA cells, which is the trade-off for working outdoors with no mains or network to depend on.
It depends entirely on your fish. Load it, run a week at your normal setting, and measure the drop. That figure is what you can rely on.
