Are matted filefish reef safe because i think it's a lie because I saw one at a lfs and it's with corals but nips at the zoanthids there and there closed up I like them but I think it's a big lie also does anyone know about elegance corals because my one doesn't look good at all it was closed up when I put a airstone in and I have turned it off it was coming out again so I thought I will feed it and it closed up and I turned the White lights off And then I saw it looked like the ends coming off the bone (skeleton) and White itestiny stuff is comeing out the bottom like loads of intestines coming out what could be wrong I don't want it to die if anyone knows please reply and i guess i will have to see what happens
