Anyone know what kind of fish this is? Looks like an algae eater type to me. Picture isn't the greatest.
Thank you. It's tiny(.5") so I'm assuming its still a juvenile. I don't know where it came from. I've had my endlers/guppies since summer and I've transferred the fry into my larger tank. That's when I first noticed it.The fish is a juvenile or adult female of Lucania goodei (Bluefin killifish).
