Should I get a red tailed shark?

I'm not great with water conditions, so I can't inform you about that side of it, but I do know my Dad keeps a large tropical set up and he's had a red tail - beautiful and got really big in there but it was a little feisty to say the least - I'd say if you have equilibrium in your tank best to leave it as it is, or look into another community fish, you don't want stress, damaged fins, etc
