The tank is older than that really bc my 10 gal was 6 months old and all the water, sand, rock, and filter media are on the tank it's cycled just going through this but yea the nem was from petco he was bleached when I bought him he's slowly recovering. I did have a green BTA but his foot was badly damaged when my LFS sold him to me guess I should have checked him out first. I also have some Zoas Palys and pulsing Xenia in there doing fine.
