Hey guys n' gals I got a new male trimac yesterday and he is still being pretty shy but is starting to settle in. He had a female mate that they were selling as a pair but I told them I didnt couldnt house both of them as I only have a 90g for him atm. He is about 7-8" and she looked to be about 5". Would they be ok together in a 90 or is that asking for domestic violence COPS style? Also if this is too small of a tank, how big of a tank would I need for them to live together without killing each other?
