i added a young discus to a 160 litre tank but my mature golden gourami attacked straight away . what can i do ?
How many discus do you have? How big are they? And you don't need to have five. Five is a good number to have so one discus doesn't get bullied all the time. It helps spread out aggression
Parameters not withstanding, tossing a single young discus into an established tank with a gourami is not the best course of action. The fact that something can be done or has been done doesn't hold that it SHOULD be done. Take time & research a bit what's BEST for what you're trying to keep. It will definitely increase your chances of being successful. "T"
