How much fish food should i feed my tropical fish?

We have about 40 freshwater fish in a three foot tank and we feed them flake and a red gritty food that normally sinks. Our fish are no bigger then an inch long except for our two black knife fish. We normally give them about a teaspoon of each a day, is this to much?

As much as they can eat in 3-5 minutes, twice a day.

that is not enough food for that amount of fish. I would feed them twice day and only what they will consume within a few minutes. If your tank becomes cloudy reduce the amount of food you give them at each feeding. If they tend to eat the teaspoon without wasting much I would stay with that amount per feeding. If they eat it all up I would add a little more of the flakes.

I would not say this would be too much food for the amount of fish you have. I would call my local pet store.

Tha's really hard to say by volume. You should feed your fish twice a day no more than they will finish in 3-4 minutes per feeding. That may work out to be more or less than you feed or right at the same. I would suspect that you need to feed a bit more though.

The best bet is to feed your fish enough to eat it in about a 2 minute period. Then from there feed them about 2-3-4 times a day.

You are supposed to feed your fish 2 x/day - no more than the amount of food they can eat in 3-5 minutes. So, start with a small amount and, as they eat, keep adding til you hit the 4 minute mark. Then you'll know. If you have juvenile/baby fish, they will need more frequent feedings.

Watch the fish feed and if they consume all food fed within ten minutes you are feeding proper amount, if food is left over feed a bit less.
