Right,
for my 120g I have decided to move my barbs up to my 20g and partition it to allow about 5g space for the
betta and 10g for 3 black ruby barbs.
My 120g currently has 3 clown loaches, 3 kuhli loaches, 1 blue gourami, 3 bn plecs (and fry not sure how many), 3 peckoltia plecs 1 featherfin syno, and 8 cherry barbs. They all get along fine atm, infact my gourami des some fishkeeping for me and is the plecs are too still he nudges them until they move lol. He has fast become my fave fish!
Is it possible to have angels in that set up? I was also thinking of getting 1 female gourami. I am 100% sure the gourami I have in there at the moment is a male as his fin is pointed and not rounded and his body doesnt seem that rounded - maybe I should add a picture

(any excuse to show him off!!)
The tank has plants around the edge and a large space in the middle for swimming around.
I look forward to your advice
