Wow, I haven't checked the invert forum in a while. Nice to see so much interest in this.
To be honest, as far as temp goes, I really have no idea, but everything seems to be going well. I started with 2 male and 2 female shrimp and both females have berried. One produced babies a couple weeks ago, so I'm getting ready to set up a tank to thin them out into as they grow cause 2 gallons is NOT enough room for 100+ shrimp. I've also added a single pond snail, which has reproduced, and a few copepods and daphnia which are also doing well and multiplying. A little sprig of bladderwort also hitchhiked into the setup and is spreading across the surface. It has turned into a pretty cool little nano invert setup. I'll post up more info and pics tonight or tomorrow
Anyone else that tries this, feel free to post pics and info here too
