Hey people, I wanted to try my first saltwater tank but was on a budget and am trying a 3g Pico. Low and behold it’s kinda hard to keep everything stable. It’s got 4 small hermit crabs and 2 zoa frags which started to close up and maybe one polyp was opening.it’s been running for almost two months but not seeing a lot of progress. Thinking about tearing down and moving to a 10g or even 20g nano. Maybe getting a clownfish pair first then getting used to corals. Please give me input!!
