It is just a small frag, the one dead was on the sand bed, and the one still alive, but opens very little. The live one is sitting on a live rock right above the one that had died.
the bubbles + my power head gets the whole tank bubbly.
ive adjusted the settings on it to the lowest it'll go to keep bubbles flowing, and still a good amount gets into the tank.
EDIT: I have a coralife 65g hang-on skimmer
