I found it in the bag of ghost shrimp and I have no idea what it could be. So if you can ID it for me, that would be great. Sorry if the pic isn't the greatest, but I have the fish in a small 0.5 gallon right now and just have the water and glass.

Looks like a tetra. maybe a blind tetra.

Tom

No, it's not a tetra, cause it doesn't have that weird little fin between the dorsal and caudal fins.

It looks rather like my Liberty Molly....mine never did get the lovely colors you see in pictures, just an off white, but the body shape looks similar.

Tom

I was thinking it was either some sort of livebearer or some sort of cyprinid. I'll check it out.

Nope it doesn't have an adipose fin and the body is kind of elongated like a minnow of some kind.

Tom

But the question is, what kind?
Tom

Butterfly

What do the fins on the bottom look like? any chance of a pic of it swimming?
Carol

Tom

I'll see what I can do. It has a little dark lateral line that goes the full length of the body, which I doubt is the actual lateral line, but it is part of the coloration.

I have included a picture here of my Libertys that might give you an idea what I was saying.....the female is easier to see, the male behind and below....

I don't think those are them. Mine is more slender and longer too.

mosquito fish.

I am attaching a couple of pics of some of mine. I have them in my outdoor pond. The larger ones are females (they have rounded bottom fins) - the smaller ones are males (they have a long thin bottom fin that is usually carried up against their bellies). The dark spot towards the back is because most of (if not all of) my females are pregnant. after all, it IS spring... Here in Phoenix, Arizona, the cooperative extension service will give away these little fish as mosquito control. They are voracious when it comes to anything that wiggles in the water. I call them my little pirahna fish because of the way they attack the tubifex worms I throw in to feed them. They like to be kept in groups. They are live bearing. Mine love to sun themselves. they will all line up against the edge of the pond in the sun and just sit there for as long as the sun in on the pond. When my pond was in full shade, they did not survive. I think they must need at least some exposure to full sun in order to survive/thrive. If they are not outside, you may consider a full spectrum light. anyway, that's what your pic looks like to me.

It could be a mosquito fish, I will check the anal fin tomorrow.

any word on if this is what you have? I'm curious to know how they do in an inside tank. I always assumed they would not do well inside as they seem to need sun exposure. Please let me know how it is doing.

Definitely a livebearer/killifish of some kind. Did you figure out if it's a mosquitofish or not? There are LOADS of fish it might be, in any case... it's almost certainly female, but it doesn't seem to have the gravid spot which most/all livebearers have. How big was it? I'm thinking it's a killifish of some sort, though female killifish are ridiculously hard to identify due to their incredibly common coloration.

gremlin

any word on id ing this one yet?

Alessa

yes im curious... it kind of has the face of a platy/guppy so like it was said before, some sort of livebearer?

mlinden84

my guess is it's a baby alligator
