Welcome to

The members of this forum have come together to share our knowledge and experiences of fish keeping. We want to answer your questions, offer advice and fill the galleries with pictures of the fish we have all grown to love.

We are a unique community of Fish Keepers who seriously take our hobby to extremes and the NEXT level. The majority of our fish collections include RARE & EXOTIC Species of all sizes, BIG FISH with BIG APPETITES and BIG TANKS.

      I have posted here about a cray in Southwest Florida that appears to be self reproducing which, to my observations, was recently confirmed after having found dozens of juvenile crayfish in a pond I have where only one crayfish existed and that since a juvenile. Any experts have input as to what kind of crayfish can do this? Here's a pic.

      It's a Marbled Crayfish or Marmokrebs. They're parthenogenetic. They showed up in the pet trade in Germany in the 1990's and no one is quite sure where they came from. Some think they're a random mutation that arose from hybridization of two species. They're closely related to Procambarus fallax which is native to Florida so they may just be a mutation of that species. They're an invasive species in quite a few countries, and up until you found them in Florida they weren't in North America. You should probably contact your local DNR and let them know what you've found, cause it's not good.
