Exactly what rob said......


Mine are all mid level and puff up nice, I have one on the sand bed that isn't as fluffy and I plan to move him up soon.. They feed for me at night as soon as the lights go out... I use a flashlight to spot feed about once a week, sometimes more if I'm not lazy... They like some flow but not to much... They will expand more in low-med flow areas..

I have a purple tang and a flame angel and no nipping as of yet.... But they are well fed, which might be the only reason I am lucky, who knows..
