i do think thats what happened the day after i was told to get a foam filter on my filter, she was stuck got her off thought in time, but 2 days later she has died so i'm sure it was the problem because the other on and the pipe fish are doing great, my bad, i had to learn some hard lessons when i start my reef 5 years ago, now i have learned one here. one that will never happen again, problem is fixed...
