Hi everybody, i'm a french guy who need some help in order to clearly identify this killifish.

It seems to be a Lucania goodei but the anal fin isn't blue at all but orange.

Several questions :

Is it truly a bluefin killifish????
could it be a sexual dimorphism???? a subspecie??? or a color-location link?????

Its history : One day, I discovered it in a tank where i display the plants for sailing.
The plants are grown in Germany.... how could it be possible to have eggs from a north american killifish in a german plant????

Thanks for help.

Genau, the fish is a bluefin. There are varieties who are more or less yellow, orange or red in the caudal. As to the fish's origin... maybe the plants were imported from North America? The plant grower kept bluefins in with plants?

thanks for information.

It could be possible... eggs on plants ... and plants in sailor tank

The plant grower kept bluefins in with plants?

I don't think so.... most of these plants are grown outside of water except some Ceratophyllum spp. or Egeria spp. I'll ask to them if they have already seen these fishes.. and if they import plants from North america.

Nevertheless, this killi is a beautiful fish and so peaceful.....maybe i'll try to buy some eggs in Aquabid in order to stock my personal 66 gallons.

See you.

He looks just like my bluefins, which are from a feeder shrimp farm in Florida. You may have better luck getting the adult fish than eggs; to my knowledge their eggs do not have a dry dormant stage.

oh??? if this information is real, so the happening of this fish in my plant tank is quite crazy because the plants are sent in box without any water...and they travel during 2 days. It seems to be impossible.....
I thought there was a dry stage????

Hopefully someone more knowledgeable than I will reply, but I believe these killifish simply lay eggs in submerged plant masses, and the eggs hatch without a dry phase. Like most North American killifishes, they are associated with relatively permanent waters (streams, in this case) and are not adapted to temporary pools as many tropical killies are.

However, if the plants were kept moist enough to survive their journey, that was probably enough moisture for the fish eggs as well.

That was my thought as well.

okay.... i understand now. How many years can they live in apropriate conditions..... (not too warm water)??? i saw on internet that their life expectancy is quite 2 years.
