My New Florida Gobies






Check out my fresh water gobies. Caught them myself in Florida canals in Hollywood.  These two species were the most common. I am not sure if they have any other gobies in there.  But these guys are the only thin I saw.  Sorry for the crappy photos.  They are pretty hard to photograph. Plus my aquarium is pretty scratched (I got for free from a dumpster).  


The goby on the top picture is Lophogobius cyprinoides or crested goby.  These gobies are pretty small, not more than 10cm.  As the name suggests, they have this interesting crest on top of their head.  Males are much more colorful, with lots of orange and black in them.




Two better quality photos of Lophogobius cyprinoides from the internet

Tasmanian Giant Freshwater Crayfish: Astacopsis gouldi



 

The worlds largest crayfish, Astacopsis gouldi, also known as Tasmanian Giant Freshwater Crayfish or Tasmanian Lobster.   Probably the most amazing crustacean in the world.  Shockingly huge.  Up to  6 kg!!!  They are even reports of them preying on platypus. I think they are also world's largest invertebrate, but quote me on it because there also giant coconut bandit crabs.  


These guys live only in Norther Tasmania.  It's the only place where you can find them.  I have not heard of any in private aquarium or in captivity in general.  That probably because they are  protected species.  They were in danger of being overfished or overcrayed))) Mostly due to the fact that they have no natural predators and lack general fear of humans.   That, and the fact that Astacopsis gouldi only breed once every two years.




Astacopsis gouldi are omnivorous, just like the majority of crayfish.  They are known to eat  decaying wood, leaves and their associated microbes. They may also eat small fish, insects, rotting animal flesh and other detritus when available.  Basically, they would eat anything they can get their giant claws on))
