Ok help in identification required for this one. Looking in the tropical freshwater shrimp dudes tank this morning and thought what on earth is that!! It's strange ….. comes up and waves around and if anything like the Ramshorn snail gets too close it vanishes below the gravel and a few minutes later comes up and starts waving itself around again. been checking on it for the last couple of hours and it doesn't seem to move it seems to be in exactly the same place all the time. My tank has got copepods in it that I keep down with the water changes since taking the tetra out of the shrimp tank and putting them into their own tank these are more evident but then again my shrimp babies are also happy the tetra are elsewhere and have a bit of a population explosion going on Ok so any ideas what this is? Not even sure its actually a worm but for lack of any other idea of what to call it …. know its not a leech which is a good thing as those freak me out lol. Ok its to the left of the Ramshorn snail in the pictures attached. And I think (and only say think) that it is feeding on the copepods ….. The snail looks huge but its actually only about 1.5cm big so a dinky really lol. @Yellowchickenparrot @pally @Heather2131 @Nigalius any anybody else who has or has had a tank really! Would like to know what it is doesn't seem to be bothering anybody just sits there waving and wafting and vanishing if anything comes close.
