Question over feeding

i know you can over feed a tank, meaning (at least to me) feeding more than the fish can eat and thus having lots of extra food settling and breaking down. can you also over feed fish? they eat every thing i put in the tank, but can i give them too much? and if so, how can i tell?

You can over feed fish. They won't explode or anything , but they can add on fat, just like people do from overeating. That can lead to a shorter lifespan. An excess of food may contribute to poor water quality, as you referenced, and in some cases can trigger breeding behaviors since food is often limited for wild fish.

A general rule of thumb, assuming you feed flakes, is if there is a significant amount reaching the bottom, the you have fed way too much! I overfeed, even though I try not to. Feed twice a day max, and try feeding them about 1/3 to 1/2 of what you think they actually need! If the foods not all gone in about 5 minutes, cut back the amount more. About the only exception to this is if you have a school of catfish to worry about on the bottom and then you can buy sinking food for them!

i feed small amounts at a time, and it is usually gone in less than a minute, with almost nothing reaching the bottom, so i'm not too worried about the water quality getting affected too much. my tiger barbs are almost always at the top front of the tank, looking for food.

DKRST has effectively responded. Fish do not need much food, and the more they eat beyond the minimal needed, the more health problems are likely to occur. A hungry fish is a healthier fish [assuming they are getting sufficient to be healthy in the first place].

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If youíre going to take it under your wing then youíre responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
