20g stocking list

2 ocellaris any variation and a goby would do well IMO.

 

Chromis end up killing each other no matter how they are added i think. i would look at maybe a smaller hawkfish, or a pair of gobies if you want more fish

 

Ya I know they will kill each other, but they tend to last longer in odd numbers. I merely said that they should be in groups of threes first to detour him from getting them and that they do better in general. A hawkfish could work but if the OP plans on having any shrimp the hawkfish will kill them.

 

I have 4 chromis in my 75g and they never fight imo. not sure if I'm going to have shrimp. Not a fan of the hawkfish.

 

Ya, I have heard some success stories with chromis. But almost always they kill each other off and many people have had more success with odd numbers

 

I'd stick to a pair of clowns and a goby. anything more and you'll have a hard time with the bioload.
