How can you tell if you feed the fish enough?

my fish pretty much tell me when they are hungry, when i walk near the tank they amass together and follow me as a cloud while i walk by. when they arent hungrey they just go on doing thier fishy business (ta dum tzzz). this is most evident in for the morning feedings.

 

I'm with Mr. Bill on this! perfect response :

 

Ha, clowns are Labradors of the aquarium . They'll eat till they pop.

 

i feed my harlequin tuskfish, niger trigger and maroon clown lfs fish frenzy 3 times a day. that still has not stopped my tusk from eating my damsels .

 

I feed any time I walk up to the tank lol. Mostly tiny pinches of flakes. I feed 1 cube of mysis once a day too.
