like at night can they see? im afraid that if i drop in a mealworm, that the fish cant see it, and it the mealworm dies, it'll pollute my tank.
not only at night, but i got alot of plants in the tank, im afraid they cant find the food.
I heard that they can actually smell the food, and they seek it out. They can find it when its dark, I've fed some when it was dark and they found it no problem.

Many predatory fish are nocturnal, using their very keen sense of smell to find their food. Corys use their barbells to sniff out food (don't know if sniff is the right verb). Most fish have great eyesight, not sure how crisp it is, but they can definitely detect movement (ie. a piece of food falling to the bottom).

I'll bet Moors see pretty well. But you would too if you had an eye twice the size of your skull! :eek:

Depends on the fish. A catfish should be able to find it. A tetra probably won't
