I plan on upgrading my tank from a 28gal to a 37gal tank, hopefully over the weekend. I haven’t finished stocking my current set up, so I’m curious on any suggestions now that I have a bit more room.
Currently I have 10 cardinal tetras in the tank. I’m going for a south American theme, since I do have soft, acidic water and a planted tank. I do also prefer to keep smaller fish. I am wanting to get a school of like 7-9 marbled hatchetfish for the top of the tank. And some sort of bottom dweller like a whiptail catfish. I will probably add a few more cardinals.. Not sure if I should add anything else. My filter is for tanks up to 30gals so I do not want to overstock the tank, but with it being heavily planted I know the filter will be able to handle a normal bioload.

You lost me at south american , im not sure what fits that bio type.
I have always wanted qhost catfish, but they need ph like yours, pygmy cories and other cories would do well too.
But get a bigger or second filter if you get a signifigant amount of more fish! You want a filter that is good for 30 gallons to 70, or somthing like that, the bare minium is not enough. Do you do a lot of tests to check the nitrites, ammonia, and nitrite. Just make sure ammonia and nitrite are zero and nitrate is not higher than 20.
