I still have my smaller 15g nano running in my basement on my FLUVAL canister. That was the holding tank for the clownfish the first 50 days. I only have some rock from the old tank and two large clusters of Waving hands Anthelia in there. I used them for phosphate control but don’t want add any to my bigger cube. I am debating resetting it from scratch and make it just a TORCH tank or all anemones and a clown.
