Sparkling gouramis fin nipping and chasing
Ive had a trio of sparkling gouramis in this tank (2 females/1 male) for about 3 weeks now, and I’ve recently been noticing an increase in chasing/fin nipping. The fins of the females have been especially nipped, one more than the other, and I think it’s the male causing it since his fins aren’t nipped at all. One of the females now mainly hides under the filter and heater in the corner, while the male has kind of made the right side of the tank his territory. The pic of the tank was taken right after a big plant trimming and filter maintenance, which is why it kinda looks cloudy. Before the trimming the left side was pretty densely planted, but the nipping and chasing was still occurring then too. Is this a serious problem that requires rehoming, or are they just still establishing territories/pecking order and it should resolve itself?
Thanks
