I've been trying to set up a colony of Crystal Red shrimp for the past year. I've tried twice before. This time I set up a tank using RODI water and remineralized it. Planted it with some nice swords and moss and drift wood. I let it sit for a month to cycle and establish. I was able to get some shrimp from a few sources going for a couple weeks now in it, so fingers crossed.
This weekend I noticed that I have a bunch of hydra on the back glass and some of the plants. Last thing I wanted to see was some pest I have to treat just as I am getting started with this tank.
