yes a jaguar would work in your proposed mix of the TT, sc's and the Bc, but adding a pike will depend on speices- maximum size and aggresion tendencies, all factors fluctuate between species of pikes. i'd probly skip on the pike and add another jaguar of different sex to try and make a pair, but if your set on them check out our forum for them here and ask for PP's help with them and which speices would work for your tank setup. i'd also be careful with the jaguars as some more than others may pick on your bottom feeders and if to small may try to make a snack, but ime with them, they can just get a bit territorial and leave Bf's alone for the most part.
