In my 60l atm I have 7 neon tetra and a bristlenose plec and was wondering what other fish would fit in well in my tank, it has a gravel bottom which is why I have a bristlenose instead of corys. and input on other communtiy type fish would be helpful as I thought about gourami but read they need a 20 gal tank cause you need 2:1 female ration for dwarfs and honey, thanks.
