Heyas there, still fairly new to the forums here. Ok well i purchased a 55g tank complete setup recently. Also included was 4 gouramis and one betta. Now the guy i got it from had the betta and gouramis together and said he never had any problems. So when my tank was setup and ready for fish i went to add the betta.....and well it seems he does not like the gouramis to much, especially the pink kissing lip one(?). The betta seems to like to flare up and chase the gourami around....then i think the gourami gets agitated and they begin swimming at each other....didnt see any biting but i took the betta out. Should i just leave him in there longer? Do you think hes letting them know where his territory is ?
