Hello! I have a 60 gallon freshwater tank. I have 6 glofish tetras 2 blue dwarf gouramis and 2 kissing gouramis. As a rookie mistake I did not research kissing gouramis and took the advice of the employee at the fish store that they would be peaceful and great tank mates however I did research and found out that they can grow to be 12 inches long! And the bigger of the two is being a bully only to the other kisser though he has not bothered any other fish that I have noticed. The smaller kisser seems to be peaceful if I get rid of the larger one do you think he will become more aggressive towards my other fish? I would hate to have to return them but I feel like the constant chasing is going to stress my whole tank out! They are both only about 1.5 to 2 inches long right now any idea how fast they will grow? Thank you! And sorry I have so many questions
