All males. And the gourami has been fine. I've had for 5 days now. We will see though.Gourami might nip the guppies, also guppies breed like crazy unless you are keeping all males.
Every Sunday I change.What is your water change schedule going to look like? Gouramis are big waste producers and poor water quality will make fish irritable and more likely to nip.
20 to 30 percent.Yeah but how much water do you change at a time?
OK. Just wondering why does this help?Maybe go with 50%
OK. Thanks for your help!It's a small tank and a lot of fish poop/uneaten food. I do a 25% change twice a week, you could too if you find that easier than doing a full 50% in one sitting.
