Need An Id

[invader]

Well, this doesn't happen to me often, but there is a fish that I don't have any idea what it is. The pics aren't the best, but I wanted to photograph it while it was still in the bag, just in case it was skittish in the quarantine tank.

Good luck with the IDing. It didn't even have a tag. I think it might be a local species, because I've seen one in a feeder shrimp tank before and sometimes native fish get into those. Who knows, though.

Full body shot:

It has a upturned mouth.

Tail shot.

Looks more like a livebearer... a gambusia or similar. Can you get a pic of its anal fin?

The anal fin is shown in the tail pic.

That's what I thought too... It doesn't have a gonopodium, if that is what you are looking for, and it's also larger than the usual livebearer (about 5").

Jeez, that sounds a bit too big for the gambusia. Sorry I missed the picture and you are right it does not have a gonopodium...

Sorry I am at a loss here

You're not the only one!

They look very like a North American native...... Fundulus species (killifish)....I cant be sure though until you get them out of the bag, settled and show their normal colouration.
Post some more pics when settled in

Looks spot on! I'll update with more pics as soon as I can.
