Fish Ideas?

[Ben M]

Hi, my brother has decided it is time to move on his kribensis and choose another fish to take its place. The tank is a juwel lido 120, (120l) and currently holds: 5 tiger barbs, 8 silvertip tetras, 3 glowlight tetras and 7 cherry barbs. what else would you suggest? he isn't very keen on the glowlights any more, so wouldn't like to up their numbers. I am looking for some ideas to put to him to help him decide and give him some options. i currently have 7 juvi lemon BN's, so when they pair up could he have a pair in there? And if so, would there be room for anything else? I've also thought of corys?

please give me some ideas to help him choose.
