I noticed the three fish has a spotted coating on them last evening that from morning pictures seemed not existent. Sent LFS a message and so we monitored. Woke up this morning found one dead, on later died and one clinging to life. We have this blue tang (dead), Japanese Swallowtail (dead) and a cow infected with much coating. LFS believes it to be ich as their tanks are not affected. New tank with in three months all fish from same lfs.
We have two clowns, two pjs, gobby pistol pair. Various crabs and snails. Parameters all stable.
Trying to learn from this experience. We were given a solution to help put a coating on them and a organic type medicine. Both dropped into tank. In Canada apparently medicine etc are banned or not available.
Thoughts?
