Aggressive Chromis

[Redhed]

40 gallon tank, cowfish(over a year & doing great) 3 chromis, Koran angel, yellow clown goby, Cleaner shrimp. Few turbo snails and hermits. Maybe 3 times a week 2 of the chromis look like they’re kissing, except, yeah they probably aren’t. So it’s aggressive behavior. Is it just a hierarchy thing?

Pretty much normal, but you are very crowded in a 40. That's too small for the angel alone so you're going to get way more aggression than you would in say a 120 or larger.

I'll be upgrading in a few weeks to a bigger tank

That's a trend.

In general chromis are very aggressive even in a big tank. They tend to pick each other off until you only have one left. They are a kind of damsel, After all.
