Frozen brine shrimp question

[FishguyAU]

Hi All, i have 10 cardinal tetras, 2 guppies and a thick lip gourami. I feed them half a frozen brine shrimp cube twice a week as part of my dry food rotation. My question is, is half a cube too much for the amount of fish I have? They seem to eat it all un about 5 minutes but the tetras bellies look big after feeding and they're not very active after eating. Thanks!

Well if it looks like they are full then that is definitely enough.

Thanks! But my concern was that it was way too much and maybe just give a quarter of a cube?

You can always try it. Wont hurt a thing. They will not starve if they only have a little bit of food for one day.
