Would never have guessed that NZ aquatic life would cause a problem overseas. http://www.mudsnails.com Quote Link to comment Share on other sites More sharing options...
Ira Posted June 1, 2007 Report Share Posted June 1, 2007 So...What eats them here if nothing eats them? Because I haven't noticed them swarming everywhere. Quote Link to comment Share on other sites More sharing options...
HummingBird Posted June 1, 2007 Report Share Posted June 1, 2007 Maybe there isn't as much food here. It's colder too. Quote Link to comment Share on other sites More sharing options...

Ianab Posted June 1, 2007 Report Share Posted June 1, 2007 Ive got a few of those in one of my tanks, was in a hurry to set up a tank and just grabbed some gravel from a local stream. Actually up on a gravel bank several feet out of the water. Anyway a few snails appeared later that look just like those. They haven't grown very much, that explains why. They just mooch around the tank acting like snails, they haven't multipied much as the pleco keeps the algae down. I bet there is something in NZ rivers that eat them, ecosystems just work that way. I wonder if the Yanks need a bucket of Koura sent over to take care of them.. but I guess that could the the Cane Toad thing all over again :lol: The Crayfish that ATE the States Ian Quote Link to comment Share on other sites More sharing options...
