Looking for advice on upgrading

[Arden]

Hello everyone. I currently have a 55g with 3 clowns, 8 hatchets, an angel and a plico. I want to upgrade but money is tight. What is my most economical solution to be able to house what I currently have plus a few additional fish.


ideally I'd like to at least have a min of 5 clowns but probably no more than 7. I think the number of hatchets is more than adiquit. I might at some point want to add some additional fish for additional intrest but nothing major.

What size tank should I be looking for. What kind of setup would be best for those combination of fish.
