What fish am I

[captmicha]

She showed up in my shrimp tank randomly and I grew her out. About 3/4" of an inch.

Least Killifish?

That looks a lot like a young Madagascar Rainbowfish, but not much like a least Killifish. I'm not an expert on either, though I keep both. It's possible eggs came on plants or moss that were in with shrimp, or in some plants you got, especially if you got shrimp/plants from someone keeping them.

I've ended up with cory cats on a few occasions after buying plants, so it's not unheard of for eggs to make it through a transfer like that.

I think you're right. Thanks.

Happy to have another CARES fish in the mix.

I have one pair left. I think we started with a school of 8 but they are really, really rough on each other.

Its a female bluefin killifish, Lucania goodei..

Even in a densely planted tank? I'm assuming but want to check.

It does also look like L. goodei.

Lots of small, olive-ish, striped fish look similar to me. I'm no good with this.

Luis had bluefin killies.

Yeah, the Madagascar rainbows chased each other to death in a densely planted 125 over the course of 18 months or so.

Sorry to hear that.
