Hey guys! Im needing some quick help... I have a colony of zoas which actually were the first ones i bought for this tank about a month ago which seem to be dying..they look like theyre melting away into themselves...all my other zoas are doing fine! I had them toward the bottom of the tank so i just moved them up tiwards the middle........the tank is a 14g biocube which has been up for about 2 months already and ive been checking the water weekly and everything has been good
