Hey HAO I have a couple of question I will like to ask you. How big is your tank? And do all of your clown knife get along well.
The reason why Im asking is because I have a 19" royal clown knife in a 75Gal tank that I will soon transfer into a 120Gal tank that is 48" X 24" X 24". I got this tank because its much wider and I will love to get another rck. I have done some research and I read that clown knife become aggressive to their own kind once they are adults
I plan to stock the new 120Gal with 18” silver arowana and two spotted alligator gars and the royal clown knife. Do you think it will be a good idea to add another clown knife
