Tuesday Night Mixer – Facebook Live Stream – Killifish

I am hosting a live stream event each week that we are calling the Tuesday Night Mixer.  Tonight was the first one, and it was a lot of fun.  The topic was how I work with killifish.  Here is the recording…  join us next week!   

Laimosemion (Rivulus) rectocaudatus

The fish that we collected on the trip to Peru arrived yesterday.  We got a couple dozen killifish, Laimosemion (Ruvulus) rectocaudatus, that we found in the ditch along side the road.  The little run is water was lousy with these killies.  We could have collected hundreds of them.  The fish is pretty and mean, and also good jumpers.  I put them into a 20-gallon tank with only a few inches of water to acclimate them.  They were spread out a day after this video was shot, but I noticed that they were doing their best to jump out of the tank, and grabbed the video camera…  Enjoy.

 

Who C.A.R.E.S…? Aphanius transgrediens

Here is a video of another endangered fish I am maintaining.  I have not had these killies very long, and have just recently been able to collect and hatch viable eggs.  The fry are growing fast though!

A few years ago I had the great pleasure of visiting the Aphanius sp. maintenance facility in the basement of the aquarium building at the Wien Zoo (Vienna, Austria).  I was not there to see the killies, and had no clue that they were even there.  What a surprise!  The program maintains more species and locational varieties of Aphanius than most of us even know exist.  Some of these little fish are spectacular, and I have been on the hunt for them ever since.

The genus is found all around the Mediterranean Sea, and all the populations are considered threatened in the wild.  Some, like the A. transgrediens in this video, are critically endangered (if not already extinct).  One species, A. mento, is relatively common in the U.S.A. hobby… and it is an excellent species to work with.  All the other species are very rare, and I thank my friend Kurt Z. in Missouri for sending my founding group to me.

“Who C.A.R.E.S…?”   This is a challenge… if you are not keeping at least one species of fish that is at risk of becoming extinct, please find a species that interests you and make the commitment to keeping them for as long as you can.  And breed and distribute them.  Check out the C.A.R.E.S Preservation Program to learn more.
