Howdy! I went on vacation for one week over the holidays and everything was fine when I returned except for my monti frag that I’ve had for about a month or two now.

Hello, I bought this porcupine pufferfish a few months ago, and he is doing well. He eats like a pig, including dry shrimp, krill, and frozen shrimp. My blue tang picks on his fins at times but it never bothered him thus I never did anything about it. But 2 days ago he refused to eat and has...

Hi all! Brand new with a 50.3 Waterbox. I did a bunch of research prior, and although overwhelmed by the many ways people suggest cycling, kinda get the gist that you want nitrites and ammonia at 0. To begin, recently bought live sand, saltwater from my LFS, and what was called "live rock"...
