Hi Coco76. The photos aren't adequate to confirm the ID. Yes, your fish look like adolfoi, but the only way to be confident is to look at the pectoral fin spines. If the spines are serrated, then you have duplicareus. If the spines are not serrated, you have adolfoi.

Cheers,
Eric

I don't think any-one can give you a definitive answer. This is what Ian Fuller (Coryman) said:

.....These two species are not always that easy to differentiate between by colour pattern alone. In C. duplicareus the black strip tends to be broader, the body slightly deeper, the snout sounder, but the one feature that will separate them is the rear edge of the pectoral fin spine is serrated, in C. adolfoi it is smooth........

So the problem is that, you need to be able to see the details of the pectoral fin spine to get a definitive ID.

Edit:
