Some advice: don't use automatic feeders for your aquarium. There are only disadvantages:
1. The food might cake together from the heat of the lamps, it is possible to disturb the working of the device.
2. The food needs to be stored at room temperature, the heat of the lamps will cause the vitamines to break down.
3. Every week fishes need to get a day of fast. Also 2 days a week it's important you give your fish frozen food to keep them in optimal health.

Feed your fish by hand each day 1 time and use the weekend or vacation food if your out.

But, if it away from lamps and used only when it's impossible to feed them by hand? Sorry about the english, my default language is PT-BR ;)

If it's impossible to feed them by hand you have to use weekend or vacation food. During non-vacationperiods you have to feed them by hand to make sure there's variation in their diet.

I have been thinking of similar device but the plans which have crossed my mind were all too difficult to construct, but this instructable is cool. It's affordable and simple! I'm gonna make it myself, thanks a lot for sharing elufo!

This looks great, I'll be watching for a cheap clock to try this!
Question: Is there a problem with the fish food missing the box and openning or does the constant rotation ensure food always gets thru the hole and into the tank?

wow. cheap, simple and easy. very nice. 5*
Feb 17, 2010. 6:52 PMtags-g says:
nice device indeed...by the way, do i need to set the clock always after every feed it makes?..or it will just go on in one set only?...
Jan 15, 2010. 5:34 AMsergey.p says:
Very nice device, indeed. I should try this as well.
My fish needs different food: chips, flakes and small sand food.
Do you have any idea to make the same kind of feeder for different food types?

First of all great Instructable. This is very similar to one I bought at my local fish store. The only issue is that if you have a tropical tank there will be some humidity. This means the food could get damp in the feeder and spoil. Again great idea.

How do you remove the chlorine ?

Just looking at the pictures on this page, I'd say that it was meant to overhang the edge of the fish tank. But, that's just a guess.

I have an auto feeder that I bought at a pet store. This idea is great as it allows the fish to get fed at the same time each day and they never miss a meal and allows you to leave on holiday for a week or two. My feeder allows me to leave for a month without worrying. Anyone have any ideas how I can keep my water level in the tank constant? If so let me know and I'll be all set for another vacation! BTW, The feeder is placed on top of the tanks allowing the plastic can to rotate freely. Thanks for sharing your idea!

How many gallons is your aquarium? If large enought you could implement some sort of device, that works the same way as a toilet, when water drops below certain point then tank fills appropriatley. Viola,
