I concur with Muck on this. The joined breakers are used for either split 110 receptacles, where each plug on the outlet is powered seperately as in a kitchen pluig, or for 220v use. The purpose is to ensure that if the breaker is tripped or shut down, both power sources, which go to the same location, are shut off for saftey reasons. Don't want to be opening a box to find there is another source of power there to suprise you. They can be used seperatly with no problem, ecept it could be a nuisance having both trip off together. The 14/3 cable is the lead that will power such an outlet. both can use the same neutral, so there is no need to run a pair of 14/2 wires. What I would do is switch that four lead wire onto the unused paired breaker for the above noted reasons, then use the individual ones for your new fish room circuits.
