Clownfish acting different with dents in his head??

[SlugSnorter]

Is there any alternative? Because my quarantine tank is 15 gallons, I’m looking for another job, and finals are coming up. There are 16 other fish in the tank as well.

velvet needs copper treatment, can you setup a few emergency tanks? all they need is a cheap bargin bin heater and an air powered sponge filter. they can even be buckets. You can use prime instead of cycling in an emergency
