a propper mated pair is close to £100. tehy are usually £30-35 odd each for really little ones. two would be fine in a tl450 imo, with not mcuh else
so as long as you are prepared and equiped to whip out one to a qt tank or box etc then go for it 
Emporer cardinal pair? Hhahahaha.. I await Seffie's disgust!! (but fishy will have my back!)
