I have been to the islands off Anilao for snokeling visit and island hopping.
yes, there are still colored fish there, but the coral reef are dead compared to those found in Bohol or Palawan.
I had been to Sombrero Island, off Anilao but the foreshore area is already dead. The fish swim around rocks, not reef.
You can learn scuba diving there because of resorts but the sceneries are not that exotic. Better dive near Bauan, adjacent to Anilao, where you can find beautiful underwater sceneries.
