Which fish would be best for a 20G?

[parker171]

Well im going to buy a fish today and was wondering which would be best for my tank, right now i have a clown and sixline wrasse in it... These are the fish im thinking of.. Firefish,blue damsel,domino damsel,royal gramma,anything else? Also would i be able to have pepermint shrimp in this tank?

i wouldnt add all those fish. maybe like 2 firefish and thats it. and the peppermint shrimp would be alright

How long has the sixline been in there? they can get pretty aggressive so... that may hurt you in the long run... maybe add a yellow wrasse... and a second smaller clown to pair it up with the one you already have..
I wouldn't add anything else if you have those larger 4 fish in the tank.
