Efflo or Monti ?

[A.G]

This mother colony died on me . However, the frag I took from it keeps encrusting so I dont know if its monti or efflo.

From the looks of the corallites i would say efflo for now. Efflos will encrust quiet a bit before they start to table out. Looks like it is getting too much light too.
