I have 12 fancy male guppies in a tank alone other than bottom feeders. Had them for over a month. They are constantly chasing and nipping 2 yellow males. I have lots of plants. How can I stop this. I feel sorry for those 2. Never get any peace.
It hasn't been going on a month. I have had them a month.remove them because the bullying won't stop if it's been going on for a month.
And do what with them? Don't they need to be in groups over 6?How long has it been going on for?
It's a fight for dominance and the weaker ones will get injured or killed, so remove the ones being picked on or the ones doing the bullying. But removing the bullies can upset the hierarchy and cause more problems.
