My first elegance ate a mandarin and died a few days later. Both the fish and coral were healthy prior. I replaced the coral and fish a month ago. Today I woke up to find this new elegance was in the process of ingesting a large sea hare. I removed the hare; however, they release a toxin as a defense. Any way to neutralize the toxin. I run carbon and I changed as much water as I had mixed. I plan on changing another 30 gal tomorrow. (I have a 120gal display with a 40gal breeder sump)
