I recently purchased 2 Green severums and introduced the my my 55 gal tank. I have and assortment of fish including pearl, gold, and moonlight gouramis, serpae and bluberry Tetras, and the "bosses" of the tank - 4 Angles. On of the severums has grown very quickly and is almost as big as my gouramis (3"-4"). He is becoming increasingly aggressive while the other severum just kind of hangs out in the corner of the tank leaving everyone alone. I don't think it has gotten to the point of him nipping fins yet, but I was wondering if anyone had some experience with this breed and if I should get him out of the tank now before its too late......
