I also have a 36
gal bowfront and I currently have around 30 fish in it. In addition to Rasboras, I have a school of Black Neons, a couple of YoYos and some Bolivian Rams and Apistos Cockatoos, along with several misc. like Endlers and Embers.
Mine is pretty heavily planted, and I had caused a mini cycle due to over cleaning my filter media, so I do partial water changes every 4-5 days. My water is crystal clear.
Maybe some would think I'm overstocked, but I'm not experiencing any problems at all. I think you would be okay adding some fish, but that's my opinion.
I tried to add a picture of my tank, but it always comes up sideways. I have no clue what I'm doing wrong....
