Help Stocking My Orca

[Dana C]

Hi,
I have an orca 550 which is 128 litres, so far I have a firefish, watchman goby, a cleaner shrimp and some snails. Everything is healthy and my water stats are stable so I will be adding another fish.
I would like a clownfish but would like to know which is the best kind to get and are you best keeping just one or in a pair?
Also are clownfish ok with what I have so far as I don't want to upset the tank?
Thanks in advance for any comments.

clowns should be fine. Get the smaller ones, occelaris or perculas. As the others can grow pretty big. Clowns are terratorial but adding them last will mean all the others are settled in before the clowns claim their turf. Buy a pair or single. If you buy two buy small ones so they are likely to be un-sexed. The dominant one will turn female
