They now rush to the cloud as I feed them... they're more visible after feeding as their stomach is filled with food xD

I feed them twice a day and do 20% water change at the end of the day

My fries are getting bigger really fast, just 1 week and they're half size of a red cherry shrimp already, I think I can tell which one is going to be red/black now cause there's a little color near their tail :). I tried to feed them with moina but they not interested, maybe some moina is still too big for them.
Should I keep feeding them with egg yolk?
Should I add floating ice packs to lower the temp now? (temp is at 28C)

You can try crushed flake food now. Just rub it between your thumb and finger to make it powdery.

I don't have flake food, I will try to get some though. People in my area prefer pellet, and I have a bottle of crushed pellet.... will it work?

So it's been 2 weeks since the fries hatched. Should I stop feeding them egg yolk and move to moina now? I have lots of clean moina!

I don't know what "moina" is.....I assume a live food? Is it small enough to fit in their mouths?

Ah, right I Googled it and it's a small crustacean similar to daphnia, but some species are very small and are cultured as fry food in Singapore among other Eastern countries. Yes, it should be OK to switch to feeding that now

Yep, at first I mistook it for daphnia
Do you have those in UK?

There are only couple of species here, in relatively localised areas. Mostly we have daphnia.

My fries are getting big and starting to show colors now. Should I keep feeding several times a day and do daily water change?
