What particular type are these?

The large one in the back I think is a discoma its about 4 inches long and has the little finger like things extending out from it, also what is a good price for these two specimens?

this is a close up of the unidentified one. as you can see it has the same bumps but none of the finger like appendages.

if it is a discoma, does it pose a threat to seahorses by eating the unsuspecting ones? Can I counter act this threat by fragging it alot so the mouth stays small?

perhaps now

bottom picture works, bump!

The top one is a Discosoma Neglecta and the bottom one is too angled of a shot to tell whether it's the same or the Discosoma Carlgreni.

The Neglecta is a potential predator of small and slow moving fish (gobies, etc...). So you have been warned.

I agree with you there on the neglecta but carlgreni isn't too close to the other maybe this image willl help on the blue one.
