how about 4 danios, 2 cories (some people might suggest tat you get 6 danios, not 4) and some pretty spotlight type fish?? i've got dwarf gouramis for my showy fish, but they need at least 10 gal., i think
Edit: new thought - why not get 6 tetras, you could get 2 different types (3 of each )
but if you'd prefer guppies, why not get 8 of them, instead of 6 small and 2 large fish?? that would look good too. my only bit of advice with guppies is that if you don't want babies all the time, only get males. they look gorgeous (tons of different types) and are really sweet to watch
I would get 3-6 zebra danios because they are cool little zippy fish they're pretty funny to watch actually . And for your big fish wait about 2 or 3 weeks and if your danios are still living get two gouramis. I have 4 zebra danios and 1 gourami and they get along just fine. Hope This Helps
