I had a few really nice acans, but then my orange shoulder tang started to pick at them until they were almost dead. I had to take a epty butter dish and poke hole in it and use it to sheald what was left of my acans.. I have never had a tang do anything like this before. I would bang on the tank while the tang was eating the acans ans the tang would just look at me and go right back to eating the acan. It just would not leave it alone... ugh..
I cant get the tang out of my tank so I had to move the acans around the tank until the tang started to lose site of where I put the acans.. What a pain in the butt..
But now the tang seems to have lost the taste for acans and all is well at the moment...
Tips for acans is to feed feed feed them as much as you can IMO.. I take cyclopsys (spelling error) mixed with mysis shrimp mixed with oyster feast mixed with phytoplankton then add a little zoaplankton.. It seems to pack a punch, my corals love it and grow awesome with awesome colors. (until Mr tang eats them)
