Remove Blue Light from Aquarium Footage

Just shot some footage in an aquarium and, looking back at the videos, the fish are blue! Everything is blue in fact. Prior to shooting the fish and their environment everything looks 'normal'. I've tried all in-camera white balance settings before recording, but nothing defeats the blue in the resulting video.

Is there a 'quick'/technically accurate way to cancel out that blue in post?

Mind sending a screenshot?

Also is this using a Pocket Camera? Very possible you were viewing in log or it got transformed to another color space.

There's a guy on Reddit who posted a colour grading tutorial for people who shoot underwater, maybe something here can help you?

The footage was shot on iPhone 11 Pro at 4K24p using Filmic Pro.

After extensive white balance testing, I opted for the preset 'Daylight', which returned the closest video to what was appearing in the tank, except where the tank was lit with dim 'violet hue' light.

Note that where the 'blue' appears in recorded video, the 'blue' does not appear to the eye when looking at the tank, but there is a dim 'violet hue' in that tank.

Screenshot 1: This tank was lit normally, so the video turned out true.

Screenshot 2: This tank was lit with dim 'violet hue' and looked fine to the eye. However, the fish should have a silver colour, not blue.

Screenshot 3: This huge tank was dimly lit with a slight 'violet hue', yet the video is very blue.
