This is the first time hearing about this are CBS known to eat Aptasia or is yours unique? My CBB doesn't touch the Aptasia at all.These guys... yes, I meant to include the picture of the shrimp. That "little" dude has been with me for two and a half years and devours aiptasia. The copperband is about two months in my system and it was clear of aipys when added, but I'm sure if one pops up and the shrimp doesn't get it first, she will eat it.
