Unknown livebearer- help me ID please :)
 
They are supposed to be platys, but after closer inspection I'm not sure.... My male platy is definately ignoring them. Perhaps a Molly?

Possibly a sword tail, this means its also an Xiphourous species meaning they can crossbreed with your platys. Most people would suggest against it

Just so you know platies and swordtails take forever to mature. What you though was a female can be a male as they take about 8-10 months to develop a gonopodium. I have a friend that bought 4 Black swordtails like me at the same pet store. She bought them a couple of months ago. She thought she bought 1 male 3 females. She told me that the 2 of them are starting to get swordtails.Mine still look like females so far. I have them with my 3 Orca black platies and those still look like females also.I need 1 male out of the 2 swordtails,3 platies.Some people think they change sex but that's not true as they look like females for the longest time.

Variatus? or is that same as platy?

eatmysox 12-18-2010 04:27 AM

Well there are a few different species of platys the most common being Xiphophorus variatus. This is what you will find at most pet stores there also is the X. Maculatus, X. xiphidium, and X. milleri. Sword tails are also in the Xiphophorus genus. I personally have a breeding group of wild caught X. Helleri but there are others that are in the hobby just not common. X. pygmaeus and X. montezumae are my next breeding challenge once I get the black bar endlers (Peocilia Endler) out and sold.

The videos are a bit fuzzy, but it looks like a Gambusia affinis, commonly called Mosquito fish due to its voracious appetite for mosquito larvae. Also a livebearer, but a notorious fin nipper, so watch it carefully as it settles in. It has been introduced to various non-native areas to control mosquitoes, and ended up wiping out local fish populations. Rough for its small size.

I thought it had color to it, I completely agree if it is just a grey but I was not aware there were color morphs to the species?

The fish in the video looks like it is basically yellowish-buff off-white. The "colour" seems to appear and disappear, I don't think it is on the fish.

Yea, in person it was basically gray..

The other ones in the tank at the pet store looked like swordtails, but I thought swordtails were slimmer... I thought it was some sort of platy with a lower sword...

*shrug* Wow, I hope it's a mosquito fish... Probably a swordtail if there are any gray ones. The stripe baffles me.

The lateral stripe is an odd red color, but it's pretty dull.. Strong, easily noticed, but not bright by any stretch of the imagination.
