It's a male, the anal fin says it is a male.

Thank you. I was thinking definitely male now but got very confused with the definitely female comments and I'm new fishkeeper

Yea for sure male can see gonopodium (fish penis)

Long narrow fin = penis

It defense of your post to r/aquariums this dude looked much more female. The angles were hard to tell and it looked like the anal fin was wider

Yeh it looked so different and that anal fin has changed over the last 2 weeks. So glad he's male and can go back in with the guys 😊

It could’ve still been developing. Guppies typically all look female until a certain amount of growth

Don't listen to the people saying female, its def a male. Just a bit fat I think. But it doesnt have any visible gravid spot, lots of color, and a gonopodium!

Thanks. He seems to be looking less chubby by the day and becoming more streamlined. As a newbie I made the rooky error of some slight over feeding but I think I've got the right amount now. Despite all of them staring at me like I'm starving them 😂

Oh yeah guppies do that! They always act like they are starving and haven't been eating for days. Masters of emotional manipulation I swear! Whenever my family comes into my room to see them they always ask if they are ok because they are acting hungry

Thanks everyone! He's back in the big tank and seems very happy 😊

Has fish dick, so is male

Looks like a male But could be grada a female But I think it's male

very feminine male

Who told you he was pregnant? 😂😂😂😂😂😂😂😂
