I have two, I believe pearl gouramis, and two gold gouramis in a 55gallon planted tank. I'm not sure if the pearl gouramis are pearl. They are pinkish-slightly yellow, about 3 inches long, and standard body type of a blue gouramis (not spots). The store called them "Assorted gouramis". The other two I know for sure are gold gouramis. The pearl gouramis are one male, one female. The golds are both female. Will they fight to dealth? Will it be ok to keep them together? Do you think they'll breed?
