Okay So ever since I upgraded tanks added a bunch a fish swapped over to 2 kessil 360 we's (all at the same time) my acans have all looked terrible for the past 3-4 months most are alive and have not lost heads but are completely sunk in and not puffy whats so ever... My parameters are all spot on and I've held them where they are consistently Salinity 1.025 Alk 8.5 - 9.0 Calcium 425-450 Nitrates >.5 ______________________________________________________________________ After keeping my params stable I moved on to lighting So I did upgrade from a Revive T247 to 2 kessil 360's when I upgraded from a JBJ45 to my Reefer 350 and I initially may have had my Kessils set too high at 100% I started ramping them down and the acans showed no interested I have have them at max 40% for 2 months straight and still no improvement I have seen a few threads here and there about Kessils being detrimental for Acans but I'm gonna consider this as my very LAST option... ______________________________________________________________________ The last thing I explored was my fish and other stock My stocking list is/was as followed: Viglimi tang Traded in Blue tang Still in tank Sailfin tang Traded in Corris Wrasse Still in tank Melanarius Wrasse Traded in Clown pair Still in tank Lawnmover blenny Still in tank Blue devil damsel Still in tank Fire shrimp and cleaner shrimp Still in tank I removed the Melanarius Wrasse and Viglimi and Sailfin tang because I suspected them of picking at the coral. They have been out of the tank for 3-4 weeks now and still no improvement! Im desperate for any kind of feedback at this point I dont know what tiny thing Im overlooking. I think acans might be my boogie coral... keep in mind all other corals look phenomenal!! I my LPS is open and colorful I have a few sps thriving as well.
