Hope everyone had a Merry Christmas, I have a bit of fin trouble and need some advise. One of my current Golden Gouramis became dominant over the other fishes and is attacking one of my new Golden Gouramis and two Blue Dwarf Gouramis that i recently added to the tank. The funny part is that before i added those three fishes, my current Golden Gouramie got along with the other fishes just fine. Now with the new additions he seems much different. I added a bit of stress coat and stress zyme to help the tension that the Golden Gouramie has created. Also occasionaly he will chase the rosy barbs for a tad bit making it seem as he is being dominant over his space. Any suggestions on what can i do to make my current Golden Gouramie get along with the rest? As of right now i have him quarantined in a net within the tank so he would stop attacking the other fishes.
