I say go CA! You won't regret the interaction you and a big mean fish can share. They are super smart and will learn your not just a person who feeds them. My RD is a spoiled little child. If he don't see me for a few hours he starts splashing and smacking the hood. As to say come play with me.
Anyone who says their isn't colorful new world fish just shouldn't be speaking of them. As their are hundreds.
You could do a breeding pair of salvini which are awesome and are next on my list.
But I'm partial to one big mean guy. Trimac/RD have been my all time fav fish to keep. I kept a t-Mac in my 75 wish every day I had kept him.
