Hey guys! Okay so today i transfered my 2 clownfish and my chalk bass into my 66 gallon reef tbak that had a large engineer goby inside. Everything was great and the fish were and still are very active, but i notice something on my clownfish's fins. Its a cottony like substance that is on the back fins of both o my clown fish, looks like strands of cotton from a cotton ball. I have never seen this before and its wierd because it is only on my clownfish, not the others..
What should i do? Leave it alone?
Perameters are good and none of my fish are stressed (even tho im sure they were when i drip acclimated them). Any help is really appreciated!
