Well dwarfs are more aggressive towards their own species than with other gouramies but other gouramies tend to be aggressive towards them. Honeys tend to dislike competition for territory from any other species and would be quite aggressive to the dwarf but, at the same time, the dwarf is larger than the honey and would probably end up being the dominant one. Also, dwarfs are more aggressive towards other colsia species - such as the honey - than to gouramies from other genus - eg: pearls. Then there's the fact that dwarfs are more obviously negatively affected by stress than honeys so the stress from having to deal with being crowded in a small tank would be most damaging to it while the honey(s) would probably survive. On the other hand, having a trio of honeys would distract the male honey somewhat - the females wouldn't be an issue anyway - while at the same time crowding the tank more. Basicaly, putting both these species in a 10 gallon is not a good idea.
