I've got a snowglobe the size of a shot glass set up. It's on the stand it came with, but instead of plugging the bottom, the globe is upside down so it is open to the atmosphere. It looks more or less like a miniature fish bowl on a wooden stand. I put a little sand on the floor of it and added a seashell for decoration and pH stability, and also planted a sprig of java moss in the sand. The inhabitant is one egg-laden scud (maybe a fairy shrimp? I'm still not sure which I have! They look the same!). I guess my request is general input from those who have gone before me in the microtank arena. Thoughts so far:

Feed super sparingly, since these small crustaceans feed on bacterial culture. Use one small pellet of a fish food containing yeast per week.

Keep from full sunlight to avoid temperature extremes and swings (and the thing is a darn magnifying glass!).

Probably only do a 50% water change every month to keep things stable.

Remove subadults once they are big enough to contribute significantly to bioload and resource consumption.

Am I missing anything here?
 
So nobody is keeping shot-glass sized tanks around here on monsterfishkeepers? Aww, come on! Doesn't uber tiny qualify as monster, too?!
 
Right. Mine is even smaller than that. I read his notes earlier, but he isn't exactly describing every exact thing he did. I can guess at where he may have gone wrong with the tank that went diatomic, but aside from that, it looks like I'm just going to have to stick to common sense.

He emailed me but, though he was polite and thorough, I found little practical use for what he knew. Here is what I made:

Sorry the pic isn't better quality, but the thing works! It's been set up for about two months now and the only unpleasant thing is a thin layer of cyanobacteria on the java moss, but if you didn't know, you'd just see a green plant in there. The pregnant female scud has several offspring surviving and I do 90% changes once per week with bottled water. I feed a tiny bit of bread once per week to encourage bacterial growth and mama scud is looking good for her age. Many at the college are fascinated and want one.
