I will be out of station for 4 days. No one here to help me. how to feed the fish ?

Don't worry about it, fish can survive up to 10 days without food, so just feed them before last thing before you leave and first thing when you get back.

Or you can as already stated buy some vacation feeders, like a tablet that dissolves gradually in the water, but the inconvience is that you are normally required to change the water after using these.

Are you talking about an aquarium or a small single fish bowl/tank?

I can't help with a large number to feed, but I know some brands of food make some large pieces of fish food that can be put in and eaten over a several day period. See what your local pet store has for sale and maybe what they can order if they don't have what you need.

There are also actually fish feeders. Like, you attach it to the side of the tank, put a battery in it, put the food in it, and it rotates throughout the day so that the food falls out twice a day.

Depends on what kind of Fish, Large or Small?

Time release sounds best, its only four days!

If there Large, Carniverous? Then feeder minows, If

they`re hungry enough they`ll find away.

So long as you don't have aggressive fish just leave them. It is suggested that you withhold food occasionally. Fish food is very high in protein- fish are omnivores. Withholding food for a few days clears out their digestive system and encourages them to eat algae in the tank. Unless, like I said they are aggressive, then it just encourages them to eat each other.

Have fun!!!

Get a Tablet that you can drop into the tank. They have them that are good for 3 days. Get that ... because they could make the tank a bit dirty. Make sure to be ready for a clean when you get back.

At your local petshop where should be some time release fish food pellets. They worked great for my fish :).

buy some vacation feeders... they disolve and let off a little bit of foor at a time, at my local pet store they have 5 and 7 day feeders.

A weekend feeder works great:)

ask a friend or buy the one-week pellet at the pet store.
