Aggressive clowns?

I bought 3 False Percula Ocellaris Clownfish - Captive Bred from saltwaterfish and they all played nicely for several months. I found out later that they dont do well in a group unless they start as babies.. which they did they were all very small when I got them and didnt have the bright white bands they have on them now.

Ive had them about 7 months and around the 5 month time frame the smallest one got aggressive with the next biggest clown. I went to work and 8 hours latter when I got home I noticed the second biggest clown was laying on a rock from being attacked so much. It died an hour after I got home.

Its been about two months since that happened and ive noticed the clown that killed the other one has gotten much larger in a short period of time. The biggest clown will periodically nip and shake its body when the other clown gets near it. I entroduced a valentini puffer about a month ago and noticed that the biggest clown fin was damaged and I assumed it tried to be dominate with the puffer and was put in its place... now I am thinking this is from challenging the other clown. Ive never seen the puffer and clowns face off at all. The clowns stay away from it mostly.

Is this behavior normal for juvenial clowns or is there a bigger issue at hand..

Very typical, they matured and the larger being female has become territorial and establishing dominance.

One of the fins by her gills was damaged bad.. now its back to normal, and I just noticed today that one of the bottom fins by the anus is damaged.. I guess this is from her fighting with the smaller clown periodically. The male clown has no damages.
