I finished out the glassware on this tank with a Soxhlet extractor body to fill in the remaining arm of one of the multi-adapters, an Allihn condenser, and a 105 degree bent adapter. I especially like the allihn for its multiple interior bubbles. I also placed a beautiful blue and yellow betta in the smaller flask. The lighting wasn't right so the photos aren't very good but it gives you an idea of what he looks like.
My wife thinks I should just have crystals or metallic objects in with them but if I don't have any plants or aquascaping then I wouldn't be on this forum right?
I'm going to have to remove the submerged LED in the smaller flask as I just noticed a huge amount of algae growing in there. Stupid nerite doesn't seem to be interested in the algae, it just seems to want to hang around above the water line.
I could envision a Mad Scientist having say Moss or Java fern in with a Betta for practical purposes.
