I'm sorry that's the only one that came to mind simply because the site I linked I'd been looking at for possible future buys (in spring) and your first photo reminded me of the linked fish. Do you have an estimate on how long the fish is? If its small (around 1 inch) try looking up nano fish, freshwater nano fish yellow, or something along those lines. I don't know how filled in the Fish Profiles
are on this site but that's another place to look.
The only other fish I can think of that looks simular too it (in body marking) is a Madagascar rainbow fish, but it finage is wrong, its missing the black in the fins.
No need to apologize. I really appreciate your help. Thank you!
It is about 1.5 inches. I agree with you about the fins not quite matching the Madagascar rainbow.
I've been looking at native fish too just in case it somehow made it in through our old water system. Is that even possible?
Just the fact that you got an egg as a hitchhiker, and that it actually lived to hatch into a fish is pretty cool by itself. Never had that happen
I agree. I really want to know where it came from and species though!
top pic makes me think blue fin killie
Wow this is the closest match I have found yet.
BUT, the Bluefin Killi looks like it has a rounded tail fin and mine has fins that comes to a point. The eyes on my mystery fish seem to be a bit larger than most of the Killifish I've looked up. I need to check to see if all the pictures I've seen are a certain sex.
If it was a Bluefin Killifish, I would think it came from local water systems. Is it even possible for something to survive in our treated tap water system?
Thank you to everyone for the help.
