I came downstairs to leave for work this morning and i found my Picaso Clowns dead in the bottom of the tank. Not sure if it was too much stress or some kind of chemistry problem, but the neon goby seems fine and the mandarin looked like he normally does over night. I guess i'll find out if anything else changed by the time I get home tonight, but I'm really questioning if I should keep going. My time is very limited and i have to wonder if I did something wrong last night when i did a water change. The salinity looked correct and the only thing they did differently was stay close to the nem in the tank and hide after i was done. They were swimming around when i went to bed so i am at a loss with this loss.
