i tried hard to get it with my cam, my copperband dosnt want to stay still for very long at all so its hard to get a closeup. It happend right after i got some new fish dang it. I lost a basset and a coral beauty angel. I think thoes were because if agressiveness in other fish though. The sailfin might have been stressed due to losing its dominance as well. And it got really sick with ich, it looked horrible. My rocks are just showing some advanced coraline growth and this really sucks that its happening now. Any chance if i leave it alone that the fish will fight it off. its not a real big blob, about twice the size of an ich spot, and he hasnt gotten any extra on his fins since. The coral beauty had one spot on its side where the scales got knocked off, i guess my two spot bristletooth tang was warring with him behind the rocks for all the hidden lair's in the tank. the angel lost. shame it was such a pretty fish. Anyway let me know, as soon as i get some time I will setup my fifty gallon tank or mabe the fourty gallon breeder as a quarintine tank, and hopefully get everything in the main tank cleaned out. Can I treat the display tank if i take all the coral out without killing all the coraline algae?Then change my display tank water and re add the coral afterwords. It sucks cause I have so many snails and crabs and shrimp and star fish and cucumbers and such. I'd never be able to catch/find them all. Any good advice?
