After 10 years of waiting, I finally have my dream fish in my new 400! I drove a total of 5 hrs. in the pouring rain to go and get him, but it was worth every single second. He was housed in a 60 gallon bowfront bc he was quote "too aggressive ". I wanted to shove the individual who sold him to me into that little tank and then ask him how he liked it. Oh well what's done is done. He now gets to spend the rest of his life as the king of my 400! I know the general care of these guys and have researched them to no end, but is there anything I should particularly know (favorite food, never feed..., worst tank mates, etc.)? Thanks for looking and God Bless!
