Ok so this "tank" was inspired by a post on nano-reef. http://www.nano-reef.com/topic/344145-my-super-low-tech-reef-jarquariums-with-diy-pj-reef It began as an experiment and while I originally made a couple of huge mistakes (...not measuring salinity was definitely one of the dumbest mistakes I've ever made) After a couple of months of benign neglect its doing awesome. I recently cleaned it to get some of the excess algae out and added some new inhabitants. This tank has no heater or flow to speak of. It gets occassional ml water changes and whenever I feel like it cleanings. I feed a few pellets every week or so. Sorry for crappy pics, hard with the curves also don't remember how to make it vertical, might change that later. There is a thriving colony of large anthropods and a large predatory black snail and at least one asterina star which have been alive and well for probably close to 3 months. I recently added xenias which unfortunately didn't make it (I also added some new aptasia and mahano aptasia (I killed mine during a water cleaning while trying to get it off the glass). I also added some a zoa eating yellow nudibrink (Not sure he'll survive for long without zoas to eat but considering most people would simply kill him I'm willing to give him a shot. I hope that doesn't sound cruel). I really enjoy trying to find him in all the algae and his color is great.
