Even if you do nothing to them, it will eventually release spores. It's just a matter of time. The best way is to solve underlying issue than to use predators. Predators will just increase your bioload, further worsening the problem. Solve the water quality issue. You may get rid of bubble algae now with predators, if underlying issue not resolved, other pests may come (eg hair algae, cyano, diatoms/dinos). Eventually, your tank will be hosting all sorts of predators.
