So everything was fine in fish world, until a day or two ago. I noticed a few white spots on one of my clowns. My clowns had been fighting, so I thought nothing of it. Now it has many more spots, so I did some research on marine ich and it sounds like My tank has it I looked for treatments, but all I found were Copper or Hyposalinity treatments, which will kill my shrimp, hermits, snails, and live rock. Another situation is that I don't have a QT. I would get one, but I'm really pressed for space. So, what do I do? Only one clown is infected, so the other clown and my Blenny are showing no signs.
