Thanks for the info, Zach! The flipped aquarium setup sounds interesting.
It's a side track, but is Cryptopus elatus ok in the intermediate range? I'm on my second. The last time, it was growing well for the first 5-6 months, and stopped growing, and gradual decline over a long time. I imagined that LOC is probably growing them warm, and my environment was too cold (60/73F), this time I'm growing warmer (68F/86F). I'm guessing that you probably know how they grow Cryptopus!
