It is probably not a Capricornis, but it is a fine polyped plating monti (as yet unidentified) with a party trick.. it develops a strong blue growth perimeter and has slightly lighter coloured polyps.
As with most plating montis it is a fast grower and will rapidly become a beautiful colony given good conditions and strong lighting. As it grows it is important to ensure it receives enough flow to blow off any detritus that accumulates.
