Really stupid fish question

[rude-boy]

Okay we have 8 fish in our fish tank, 5 of which are minnow type things.

3 of these have rather large bulges underneath them.

Answers as to what might be going on here please.

Oh, and it isn't a swim bladder infection I'm 99% sure.

Nursery web spiders?

Eww - Nar, not them!

What kind of fish are they? If they are guppies, then 100% they will be pregnant. If they are really minnows, I think they are egg layers so it's doubtful...

Edited to add:

Does it look like this?



Even if you have no males in there, the females can 'store' sperm for over 6 months and have many batches of fry. They are nicknamed the 'millions fish' due to the speed and ease that they breed.

Where is the "just needs the toilet, but can't go because SOME PERVERT keeps staring at me" option?

they're bloaters

stop feeding them and it should sort itself out

If their eyes are bulging too they probably have dropsey.

Given your indicated knowledge, i'd go with the 1% option that it is a swim bladder infection.
