Overweight Fish?

[Ny82]

Hi everyone, is it possible for fish to be overweight? I added a shoal of neon tetras today (were meant to be 8 but there's 9) and that's when I noticed how streamlined they were compared to the others.
I have 4 long fin leopard danios 2 of which are quite chubby (the ones with the smaller fins and they haven't got the shimmer the other 2 have got)
I also have 4 platinum tetras which were streamlined a month ago but now 3 of them have big bellys too. Am I feeding them too much? This is my regime:
Monday - brineshrimp from the pouch
Tuesday - flake,
Wednesday - flake
Thursday - frozen brineshrimp and an algae wafer at night (the corys love them)
Friday - flake, peas
Saturday - brineshrimp from the pouch
Sunday - flake
I have 2 filters, the old one from the old tank and the new one which is turning brown, the water stats are always spot on but I don't know if maybe there's something else going on.
Here are some pics

These are the platinum tetras when I first got them about a month or so ago

and now

And the danios

this one in particular looks like it's going to burst

In comparison to the one with the biggest fins

These are the best pics I could get the danios zip about very fast.
Thanks

feeding regime seems ok, but it will depend on how much of that food you are feeding. How long does it take the fish to eat ALL of the food?

I was also going to suggest that they might be constipated, but you are feeding peas (crushed first, I hope?) and they are a great gut clearer!

When I put the flake in the danios are always the first to the flake, they eat it quite fast, then the tetras are underneath them catching the falling flake, the gourami is a gent and he just lingers about and only sometimes goes to the top to get flake, he usually eats the falling stuff too, then the corys get whatevers fell that the rest have left.
The brineshrimps a different matter, if it's the frozen block the danios and tetras go up straight away like they've never been fed lol then the gourami comes up and he eats it from the block and the rest eat it as its falling then the block will fall to the sand and the corys finish it off. That could take about 5-10mins.
If it's the one's in the pouch, I have to go and get the rest out with the net/syphon.
I boil the peas in the pod and then get them out and squash them in my fingers and put them in but I always have to fish them back out, they go and investigate then just leave it
