i got some pallys in a trade from another website, got them in the tank after aclimating them and what not.. well lets just say since i put them in my tank is having a major crash! all my corals look like they are about to die! i just did a 30gallon WC and will do another one tomorrow or the next day, could it be the pallys i just put in? they are the only thing thats changed in awhile.. what should i do?!
