Can guppies handle 82-84 temps? If so, then they would be fine together.

clawlan its your fish. If you want to ignore and/or disregard the environmental needs of a particular fish, it is your business. Just make it clear that you are doing so, and don't encourage others to do the same without cautioning them first. Standard care of rams - I assume we are talking about BLUE rams, not Bolivians here, is that they require warm temperatures to be happy and healthy for long. They are a savanna fish, coming from hot shallow little pools.
