I've just cleaned up my main tank, and now have a bucket full of excess Java Fern, some big established sections, lots of medium, tons of small shrubby starters, plus a couple of tennis ball bunches (compressed) of Java moss, looking to swap for some livestock - tank has a small angel, a lonely neon tetra, two bristlenose and an albino cory, happy to take anything that will work with them, guppies/platys included.
It's from a clean tank, no snails, no diseases, established for four or so years. There's a few pieces of water sprite in there, too. Am in Adelaide. If you want to buy some plants I'm happy to sell and find some fish locally.
