I am currently running a Fluval Evo 13.5 nano reef tank. I have just recently upgraded to the AI Prime 16HD reef light. I have stable parameters that are all within the correct levels; yet my fish keep dying. I have a cleaner shrimp, 6-8 various snails, a small starfish (not sure which kind but it only stays in my sand), three hermit crabs and a conch. I have several coral one LPS and a couple SPS. Everything in the tank is thriving, apart from the fish. I have now gone through 3 separate pairs of clowns, a sixline wrasse and two damsels. I have gone to my LFS and asked and they’re perplexed as well. Can anyone offer some help? I am providing pictures of the tank as well however I don’t have any filters for my phone so bear with me.
