That sounds awesome! Except for more than a true pair of angels or 2 (or maybe 3? hard to sex) females...no matter, any other gender mix, there will be trouble! Corys, or loaches... guess what I'm going to say?!? Yeah, or corys, lol! Really both are fun...said the loach lover! Sidthimunkis are so entertaining but more expensive... what can I say...you get what you pay for sounds so loach snobby, lol! If you haven't tried loaches, this might be a good chance!
Instead of angels, have you considered a trio of pearl gouramis, 1 M, 2F? Just an Asian thought...bwahaha!
