Aquarium Advice FINatic
Every night before bed, I check my tank while moon lights are on to see if everybody is doing ok. Last night everyone looked happy and healthy. My main lights don't come on until noon and I didn't think to check the tank this morning until I saw the lights come....Apparently during the night ( or maybe even before that ) my urchin died. All my soft corals were closed up and giving off some sort of slime. My xenias looked dead. I only have softies and zoas in my tank. The two clowns looked fine but my serpent star looked kind of like it was in a coma. I tested the water and the nitrates were about 25ppm. No ammonia. I did a major water change (about 40% ) Anything else I can do or is my tank doomed.
