Like the title says, need a blue velvet nudibranch for a flatworm infestation. I know these things die after they are done with flatworms. So if anyone has one that just finished clean up, I'd love to take it off your hands. Thanks!
Used it, and it does work very well. I've done 2 doses, and I still have a few left. All of the toxins released by the dead ones did have a few adverse effects on my tank, and would rather fight it naturally!
