Yes. I can find internet "research" to prove that red=5.
I can also do relevent research from actual fish keepers on the subject.
And for the record, my tank is bigger than a 180. I'm a home owner, and make a good bit of money. I can get as big of a tank as I want, and I will not be keeping my Dovii in a 180. If you can afford it, and have the room, by all means, go bigger. It's great for the fish. But if not, a 180 is fine as long as you don't happen to get the 1% of Dovii that get as big as Mel's.
