How much food to feed nano fish and how often?

HI all,

my tank has approx. 40 nano fish (Green neon tetra, lampeye killi, chillI rasbora). I do feed them variety of food (flakes, frozen cyclops, frozen blood worms, dried baby brine shrimp), but I'm not sure about the amount and how often. I leave home around 6.30AM and come home around 6PM Monday-Friday. For now I feed them once a day during weekdays at 6PM and twice on Saturday and Sunday (8AM and 6PM). Its in the weekends I feed them cyclops in the morning and sometime flakes or bloodworms in the evening.
Today I noticed they saw me coming in and was swimming on top and waiting for the food. So they seem really hungry.
Normally when I get close to the tank, they school and hide a bit in the back of the tank, but not today.
Should I start feed them twice a day? I heard some fish require 16-24 hours to digest the food?

How often and how much do you feed your fish?

Thanks!

 

~20 dwarf cories get a tiny pinch of food each night. Maybe 1/8 tsp? they seem happy.
I just salted the tank with black worms as I added Black Tiger Darios so they need live food to hunt.

 

I have green fire tetras and ember tetras and feed them twice a day. Once in the morning (flakes or pellets) before work and once when I get home (frozen daphnia, BBS and bloodworms).. I also will put in a small amount of tubifex worms that they can eat if they get hungry while I'm gone.

 

Thanks all!
I think my portion is around 1-2 tsp for flake food or 1.5 cube when feed them blood worms. All food seems to disappear within 30 min, so I don't think I'm overfeeding them.

 

I feed my dwarf rasboras 3x a day with hatched baby brine shrimp and bug bites and occasionally I'll substitute one or the other with some fry food that has some veggies in it.If you can keep your water parameters in check I think most fish enjoy eating several times a day(or maybe I just enjoy plump little nano fish).
