What's the best considerate of goldfish?
Answers:    If he is aggressive, there is obviously any not enough females for his likes, or the tank is too small. Make certain you are giving each guppy an ABSOLUTE MINIMUM of 3 gallons each, as they are fast swimmers, and obligation their space. Also make sure you have three females for every mannish in the tank, because male guppies entail this variety. Also check your water, the nitrates/nitrites could be too high, which is making him stress out, which next makes him aggressive.
