Hi guys, it's my first post so please be nice 
I've recently set up a 75gal/4ft tank w/ a Fluval FX6.
I haven't got any substrate in yet (am waiting for it to be back in stock) but I am planning use CaribSea Torpedo Beach, which is a coarse white sand. The background is plain black.
The tank currently contains:
1 x Red Severum (my pride and joy)
2 x Green Severums
5 x Peppermint Bristlenose Catfish
The Green Severums may or may not stay. I kind of bought them on a whim because they were cheap. All the fish are still pretty small so space isn't an issue yet. I guess we'll see how they go once everyone gets big.
The Peppermint BNs were given to me by a friend and are still pretty little. They ended up in the Sev tank because I thought I might as well get the Sevs used to having little tank mates now while everyone's still a baby rather than deal with aggressiveness down the line. These can be moved to my other tank if need be.
Anyway, my goal for this tank is for it to have a couple of really unique/personable sort of fish in it. Hence me getting the Red Sev. He is only a baby and he is already stunning. I want another fish that is really unique and that stands out. I want this to be one of those tanks that non-fish people get a kick out of.
I was thinking some kind of unique Catfish? I am also considering a Freshwater Crab. What are your thoughts. I want something non-cichlid because I really don't want to have to deal with aggression.
