This newbie needs some advice and I hope this is the right place to post. I've had a Coral Beauty in my display tank with two skunk shrimp for a month. He started showing signs of lymph by a white cauliflower bunch on his upper fin. Then a small one on his right fin. No changes in these two for a long while. Yesterday I purchased 2 snowflake clownfish.Now this experience was incredible. It was a warehouse in Madison where they breed exotic of clowns. The place was well cared for and I was impressed with their standards. I seen thousands! Anyway, now the clowns are in QT, all going great. Murphy's law: Today the beauty has a new spot on its side of the body (clumpy like cauliflower too, he's in the display tank where nothing has changed). So, should I swap the clowns to the DT and the Beauty to QT to treat? Now if it is lymphocytis it's just vitamins and such? Will that show up on the body too? Or am I seeing ich? Water parameters are stellar, with 2 different tests. 1.024, ph 8.1, temp 78, ammonia 0, nitrite 0, nitrate <5. Currently trying to get a pic
