are these fish healthy?

[Adler]

is it possible to cure an unhealthy fish from a LFS?

I ask because of the lack of pigmentation on the belly of the fish. check video:

If they have vibrant bold colours they are healthy.
I got a swordtail girl for free over a year ago from my lfs because she had finrot, her fins never grew back again.

The gourami look good at first glance

The pale bellies could be female or just young fish of any gender. Are these in your 20g? I forget your tank...tell us again please.

I think I see a gold & a 3 spot gourami (same species), maybe a dwarf or 2... &...?...I'm hoping it's not a balloon gourami I see...

no, they are not mine, these are from a LFS. I've never seen gourami like these that is why i asked.
they are sold for $2 each, i doubt there are any other specie than 3 spots because of how cheap they are.

long story short:
because of covid almost all businesses here were closed down because of quarantine including LFS fish supplier, so for months LFS didn't have any fish at all until recently and now that i see these gouramis i thought that, in their rush to re-stock, they put out unhealthy fish.
