Help Adding More Fish!

[chrisrm]

I have just upgraded from a 60l tank which I had for about a year, to a 350l tank. at the moment i have...
1 opaline gorami
2 angel fish
1 Otto
2 Female bettas
1 featherfin syno

I was hoping that someone could suggest some possible fish to add, as i made mistakes with the smaller tank the beginning, but have learnt.... a little! I was thinking maybe silver dollars, dwarf gourmi, giant danios, mollys? Someone suggested a pair of rams or kribs as well, but I’m hoping for some advice

i think you should get red of the gourami coz them and the battas will fight and add atleast to more female bettas.
a pair of bn plecos or pair of kribs,rams or apisto
