What happens if you overfeed fish?

Will they die? get sick? just leave what they can't eat to rot?

Is it fish-dependent?

I've heard fish will just eat and eat until they die. True or False?

fish can literally eat themselves to death. like humans, overfed fish have a significantly shortened lifespan due to increased lipid peroxidation and impaired antioxidant enzyme function. is it species dependant? i have no specific data to that effect but would guess so.

Basically you get fat fish that poop a lot and nasty water unless you vac a lot. Fat fish are no healthier than fat humans.

fish can get fat just like people can.

if you are feeding and there is food laying around the bottom, you should feed less and get it out of the tank before it rots and causes ammoina problems.

yes the extra food if the fish dont eat it can cause problems with ammonia spikes as it breaks down.
