We just returned from Tubbataha and stumbled on this app while trying to ID some of our photos. Unbelievable number of relevant photos and associated text for the Philippines. Text explains which fish are local so you don’t get misled by more general references. The photos are bright and clear with text to point out specific id characters. Also the interface seems to be without glitches in spite of offering multiple ways to search for fish info.
Great for IDing a wide variety of fish!

We’ve been diving a few sites that are “off the beaten” path of many standard trips… this app has been great at helping us identify many fish that just aren’t quite as common! I love the display of the juvenile + adult too. It’s so helpful in seeing the differences side by side! SO HELPFUL!!! Thank you!
Indexes added to Common and Scientiic Names tabes for easier browsing / searching. Some photos improved, a new species added.
