Hi everyone i'm new to this forum. So I was thinking about getting a new tank (i have a 5 gallon betta tank currently). And since i'm out of my tiny apartment I really want to start a freshwater community tank (a 20-30 gal) now that i have the room for it . i was thinking about another betta tank that would be 20 gallons with some rasboras or tetras and maybe some cory cats but i was also looking at other fish since i already have a betta. i kinda want a focus fish for the aquarium (like a betta) that would be solo. i was looking at red tailed sharks which are so cool!! and maybe some barbs, but i would need like a 50 gallon and thats a bit too much for me right now. so i was wondering if there were any other fish that could be like a focus fish (or solo fish like the shark or betta) with some schooling fish (as lesser focus fish) that could fit in a 20-30gal?
