I got it here in central Washington state (the first time I had ever seen it before). The water temp where it came from is probably in the high 40's (*F) right now...but in the summer it gets pretty warm as there is very little water movement where it's at. The substrate where it came from was putrid silty muck. My DIY CO2 ran out a few days ago and I haven't been able to hook it back up because I was resealing the cap, and I've noticed that a few of the plants are wilting a bit. Coming from the substrate it did, I'm sure it benefits from plenty of nutrients (which it's definitely not getting from the inert sand/gravel in my tank)...but other than that it looks to be doing great.
HeyPK, drop me a PM.
