Buying new clownfish

[Cage]

Hello,

Due to a recent algae outbreak and stress i lost one of my little clownfish clarkii's ( i had 2).
Now i was wondering if i could put a new couple of clownfish Amphiprion Ocellaris in the tank with the 1 remaining clarkii.
I have a 80L (sorry i'm from europe) aqua medic blenny.
Would this work with or would there be to much aggression?
Ps; i have no other fish in the tank.

Different types of clowns are more likely to fight and clarkii are super aggressive.
