Help to ID these fish?

[Seafan]

I took these pictures at the zoo and public aquairum. this one is the most curious, someone suggested it's a sculpin, but I checked all the pictures of sculpin on fishbase.org, and none matched its color/pattern -

I guess this one is a grunt?

this stringray was pretty big -

TIA!

checking all the pictures of sculpin is quite an undertaking.

Second one is the Emperor Snapper (Lutjanus sebae), third is the Honeycomb Stingray (Himantura uarnak).

I'm not sure if this is appropriate, but, Luiz, I just wanted to give you a shout out. Your photos and information are such a great addition to RC! Thanks.
