Glad I spotted this as I was just about to create a new thread to share it
Dave's videos really are of exceptional quality and I think UKAPS members should do all they can to support his work.
I strongly recommend watching ALL his other videos, especially the more recent ones with the extraordinary high definition, high magnification lenses - must have cost him a fortune!
What can I say? Superb! Excellent camera work. So much breathtaking detail. Last year, two of my German Blue Rams (GBRs) spawned. As soon as the fry had used up their egg sacs, I fed them firstly on a paramecium culture and then on freshly-hatched Artemia. In total, I had 41 healthy juvenile GBRs. It was very demanding and time-consuming but well worth the effort.
