Koran angel

[Djhgksga]

I keep a korAn angel in a tank with triggers and a puffer and the Koran is the newest in the tank it looks like it has white spots forming on it's fins but it is still eating and very active is it something I should worry about?

Newly arrived Angels are like Ich magnets!!! You need to separate him and treat for Ich as I would be pretty certain that is what it is. More research should be done to be sure. If its a fish only SW tank you can bump up the temp a few degrees and take the salt level down to 1.015 or so for a couple to a few weeks. Its good if you vac the substrate to get rid of the parasite completely. Many times if you do not vac the Ich come back like TWENTY times worse in a few weeks.
