This is at most a 1L jar(large instant coffee jar). I'm thinking of upgrading it to a 1.5 gallon glass cookie jar at some point soon.
I kept the water from some aquatic plants that I purchased and decided to do a jarrarium with it. Inside this jar, there's one little sprout of a plant that hitched a ride, and a singular bladder snail in an old instant coffee jar. It gets a little bit of light every day. Recently, my population of tiny crustaceans has exploded! It started with just a few little critters.
At least four mature hydra in this jar and one bladder snail. I'm super fascinated. This is my first jarrarium after stalking the sub for a while. It's been established for two months now.
As I'm fairly invested in the Hydra, how can I make sure I properly move them into the larger jar? I know they're basically impossible to kill, but I also know they attach to the glass.
Do I need a substrate? They don't currently have much, just what came with the plants.
I haven't added an air stone to this little tank, but I can add one once I set up the larger jar if it's recommended.
Any other thoughts and recommendations are always appreciated.
