What fish do i have?

[r2danny2]

Hi I wonder if anyone could help. I acquired a tank with fish through work. As I didn't buy the fish I was wondering if they had a name of what type of fish they are. Male or female etc



Thanks in advance.

You have swordtails.

Thanks. So are these both male. I have read up in them and it seems they should be male. Although I swear one of those had babies.

The black one looks like a female. Does it have a sword ?

The two at the top

Of the pic are the only ones with 'swords'

The black fish is probably a female then

Having a sword doesn't always make them a male. You can tell by their fin under their tummy. If it is thin and pointy and isn't usually flared out, then it is a male. If it is fanned out and rounded, then it is a female.
