How do you know when your fish have been fed the proper amount of food? It seems that no matter how much food I chunk in the tank, the eat like crazy and neve seem to get full.

I have in a 125 gallon:

1 yellow belly blue tang
1 yellow tang
6 green chromis
2 anthias
3 PJ cardinals
2 O. Clowns
1 yellow head golby
1 blenny

We feed 2 times a day some home made fish food equivilant to a few cubes. Small pinches of flake several times a day. We also put out seaweed 3 times a week. All food is conssumed wiht in 3-4 minutes.

Is this enough? What are the signs that I am under feeding?

Oh...evey one looks bright and healthy...

thanks!
