Well.. I *was* going to say get cichlids! The only thing dwarf gouramis are good at doing is dying
However... most cichlids will nip fins if not outright kill your guppies. It might not even happen right away but there is just a very high risk. Guppies are arrogant, flappy, hyperactive little things. Very much like unmedicated kids with ADHD after being fed on a lot of fizzy drinks, sugar and E numbers and then given a whole load of brightly coloured long floaty ribbons.
Who wouldnt want to snatch the ribbons off the children after they had come rushing past for the tenth time floating them in your face!?
Thats how i see guppies... if i was a fish... *i* would eat guppies!! As pretty as they are... they are incredibly irritating to other fish, therefor fish that are even remotely likely to take a nip or have a short temper shouldnt really be housed with guppies. Its tempting fate and sooner or later.. the cichlids will get hacked off with the guppies.
That aside, i have found dwarf gouramis often have a good nip at the male guppies too!
Honey gouramis would be really great! If you *do* want to push the cichlid angle... stick with something really laid back like Bolivian Rams, Laetacara curviceps or the Thomasi butterfly cichlid. Personally i would avoid the normal 'blue, german blue or gold' rams and definately avoid kribensis!
