I'm to the point that I'm ready for fish in my 180 gallon tank and I was planning on starting with Clownfish. I have 2 that have been in a 40 gallon tank for around a year and a half, but I was hoping to get a couple more for my 180 gallon tank. I know that Clowns can be very territorial, especially with newcomers. With that being said, what are everyone's thoughts about introducing the 2 older clowns I have as well as 2 new ones I buy all at the same time to the 180 gallon. I would buy 2 new ones that are smaller than my current clowns. Thanks!
