Why are my guppies getting rlly bloated?

[Navfish]

Hi, I bought some guppies a little over a month ago and I’m realizing that some of them are getting rlly bloated. I don’t know if it’s from dropsy or overfeeding. I have 5 guppies in a 10 gallon. I just don’t know what to do!

Here is what one of them looks like!

Bigger pictures would help but they just look well fed

As long as the fish are eating well and doing normal coloured poop, don't worry too much.

If the fish suddenly get fat overnight or within a few days, then it's time to worry.
