The biggest reason people want it on video is;
Prove your theory is correct, prove to us through video evidence that this will work for any fish and that fish don’t show osmotic shock.
I think one thing we need to remember is our LFSs (and we have more LFSs than America) will have their holding tanks set up FOR a reef tank’s parameters. The US in a way doesn’t get the luxury we do, their stores for fish are often online and they tend to ship fish in much lower Salinities than our LFS’s sell the fish in. The other thing is LFSs tend to be just a hours/half hour drive whilst they have fish shipped over night.
I personally drip sensitive fish - I’ve seen Floating being more stressful to them and I have lost sensitive fish due to floating whilst I rarely lose those fish due to dripping.
When I say sensitive fish, I’m talking Regal Angels, Achilles Tangs, Copperband Butterflies ect.
I will float hardier fish such as Clowns, Fairy Wrasses, (Smaller) Foxfaces ect.
The other time I will drip is if the fish in the bag is too big to stay in the bag when it’s closed. I have dripped a 3 inch Magnificent Foxface because of this and I also dripped my Regal Angel because of this (as well as it being a sensitive fish).
Here was my most recent drip when it comes to fish.
And the last time I remember floating a fish was this guy.
I can speak for both ways and by far I prefer the drip for most fish but other fish I will happily float. I hate floating sand sleeping wrasses as they just try to go down into the sandbed and risk mouth damage.
