I've had that fever and expensive is right. Magma would be a good guess but the strain has been bred & cross bred many times. The original red magma used to be intense red and the more recent strains are more pinkish red but still holds the worm pearls on their cheeks as yours does.
Males of the ZZ strain tends to be more fertile from my experience in breeding flowerhorns and kamfas are hit or miss...unless you know of their history. Throw in a female parrot/kkp/mammon with any fertile male, You'll likely produce a sterile male. The best bloodline (great markings, huge kok, intense color, uniqueness...etc) will fetch the highest price.
Based on the black marking on its dorsal fin and short fins, I'm comfortable in saying yours is a female. A pic of its breeding tube will help. Only sure way is when it produces eggs. Males can be sterile but I have yet to encounter a sterile female. I have noticed some deformity or odd shaped & size of eggs in several females, where the smaller ones could not be fertilized.
If you're interested in breeding her, search for a nice fertile male...ask the breeder of its background and ask if it's fertile. You already know, nice ones will cost you...better than settling and introducing more junk fish.
