That's a picture I took yesterday. I have 3 pearls, 1f/2mLooks like it! Can you get a pic from underneath? How many pearls and what sex do you have?
I can't add more gouramis, they are just fine together and I already tried adding other pearls but they didn't accept the new others. It's a 55 gallon 4ft long. The biggest male claimed the left side as his territory and the smaller one stays most of the time at the right. The female really goes anywhere but she get chased by the males sometimes. The biggest male (the one that did the bubble nest) is colored up right now, very beautiful!Yep, that's a bubble nest! Love is in the air! Word to the wise, though: it's better to have more female PGs than males. The males can get sort of obnoxious when The Urge is upon them. How big is your tank? If you have space, you and your critters would be happier if you either got a couple more females, or got rid of one of the males.
Are your males all colored up? Mine would always get really beautiful when they' were trying to impress the gals.
