I am thinking about turning my 30+ gallon tank into a community tank with a single betta, few maybe 4 or 6 cherry shrimps and same amount of neon tetras or maybe something else. I knew bettas are very territorial and made this decision after some research on the internet however people keep suggesting me not to keep betta in there and the shopkeepers keep saying get angel fish instead. All this has made me confused about whether to keep a betta or angel fish or simply just keep a few goldfish (ranchus and orandas). This is my third time keeping fish. My first 2 times weren't great as I kept going according to shopkeepers and didn't do my own research. So my question is whether I should go with the shrimps + tetras + betta or shrimp + tetras + angels or just goldfish.
