Sticklebacks are coldwater fish and should not be kept in heated tropical tanks. Did you know that sticklebacks are protected species in many states and cannot be collected?
From a bait shop is OK. They're most likely not carrying one of the protected species. However, still coldwater and not a candidate species for warm water tanks. 72F is max temp for short durations. 68F and below is preferred.
