Unable to find the last coin in aquarium in Chapter 3!

Not sure if this is a technical issue (with the game, not my brain), but I am unable to find the last coin. I checked the strategy guide as well, and I am sure I found all the ones that I could. This is on an iPad in case that matters.

Here the screenshot when trying to use the hint question mark to find the last coin:


Any ideas what I can do?
