I want to put shrimp in my cylinder but I was told they wouldn't live in it because it's unfiltered. pH is 7.5, hardness is 10, and nitrates are 5.0ppm and ammonia 0. I do a 40 percent water every 2 days with dechlorinated water that sits open for 24 hours. And it's well planted. Any thoughts would help. Thanks!
I had PFR shrimp survive in a moss only tank, no filter or substrate. They breed non stop. I also kept one PFR with few chili rasbora in a Walstad bowl and they love it. Everyone survive in that bowl for about a year before I tore it down and move them to another tank.
PS: Your cylinder about 4 time bigger then my bowl so you can probably keep a breeding colony of shrimp in there.
