Corrected entry: The singularity that consumed Planet Vulcan simply closed on itself, yet the singularities that consumed the Romulus sun and Nero's Narada ship, each with different amounts of red matter used, either stay open to pull the Narada and Jellyfish in, or tries to pull in the Enterprise.

Correction: Different cases. The circumstances are different each time, different amounts of red matter, one opens within a planetary core, one within a ship, the third within a supernova shockwave. Given that the whole thing is made-up science anyway, it's impossible to say how the red matter singularities should react in any given situation.
