Identify these snails and this fish

[Torrean]

I will try to get a better pic now but I don't know how good it'll turn out. The little guys quick and the sun hits the wall behind me when I am trying to take the pic so there is a glare during the day. BRB with better pic hopefully

BTW the link (in jflower's post) is to gambusia affinis which is the 'western mosquito fish' The 'mosquito fish' is heterandria formosa.

I think I got it. Wait just a minute and I'll get the pic on here

The 'long fin that sometimes points down' would be the gonopodium - a modified anal fin used to internaly fertilise the female's eggs with packets of sperm. Only the males have it so the fish in the link I posted (which is a female) has a fan-shaped fin instead. The fish in the link jflowers posted are the same species but some of them might be male - so they'd have a gonopodium like yours does while the females would have fan-shaped fins.

does this help???

edit: the first and third ones show the gonopodium
the first one it's down the thrid it's up

I think it's deffinately a male gambusia affinis - it even has the tail pattern and the dark mark below its eye where you can see its internal organs.

ok so what does that mean? thanks a lot btw. What i'm asking is basically how big does it get?

 

[sylvia]

lol - don't worry it's about the size of a guppy at 1.5" and requires the same basic care too.

edit: forgot to mension that they are a little nippier than guppies though

I am sure thats the one.

Size differs from what I read from 1" to 2", think 2" is probably females and 1" males.
