Best fish to add to 75g with only one clownfish

I recently purchased a 75g tank set up for FOWLR. Came with lights, pump, heater, skimmer, live rock,, sand and a lone clownfish. I moved it and kept as much of the water as I could since it was a short move across town. Anyways tank has been up and running for about a week and a half with no issues. So, I'm looking at adding a friend to keep the clownfish company. What is the best type of fish to add? would it be ok to add another clown? Open to any ideas as I'm new to the hobby and don't know much about compatibility.



Thanks
