CUrrently 4 fish

I took out a damsel due to bulling my yellow watchman goby with his tail.
*anybody seen a fish attack another fish with a tail slap?*

Anyway today I got $4.99 credit from lfs for my damsel, and added a fire fish. So currently my bio-stocks are...

2 clown
1 fire fish
1 yellow watchman goby

4 fish total. Will it be safe for me to add more fish later on? like 1, 2 or 3?
Because I was interested in adding like 2 or 3 chormis, cuz i have heard they are school fish, and pretty cheap.

 

I would not add any more. Pretty well stocked as it is. In my 29 i had last year i only had 3 fish in it.

 

ah okay thx
