are these regular silver dollars?

[EVP]

their anal fins have grown a lot since I got them 2 weeks ago (they were beat up) and they have grown white tips on the fin.

Could be juvi red hooks i cant tell.

 

[EVP]

thats what i was thinking. they were half the size of the spotted i picked up with them, now they are almost the same size as him.

not true redhooks as even small ones display the pronounced 'hook'

still, very nice silver dollars

 

[EVP]

ive been searching for pics and can't find any SD species with a white tip on their anal fin.
