Antibiotics? updated, with pics of my sick fish

[Reef_kid]

maracyn is erythromycin... it is a broad spectrum antibiotic so it should take care of most bacteiral infections however if your using it in a reef tank with live rock it will kill all the other bacteria that are gram +
however if your treating a bacteria that is gram- all it will do is kill other bacteria that will in turn posion your fish with antigens and toxins

best thing to do would to get the fish into good clean saltwater from your main tank increase the tempature a few degrees and the salt concentration

trisulfa drugs may also be another way to go since is commenly used for popeye infections. but again use in a tank with freash salt water
