They do acclimate, but what's the point of showing acclimation on tv? Like watching paint dry on Holmes on Homes.
The show is cool because unlike OCC they all get along, no major fights like all reality shows, and they are goofy and they make cool tanks!
However, most of their tanks are NOT pratical. Hard to clean and maintain. I've seen a fridge tank that was AMAZING a few weeks ago, but how does someone clean a 9 foot deep tank with shelves and items in the way?
Also they had this cool phonebooth tank that again was about 10-12 feet deep. the top of it had like a 3-4 foot clearence from the ceiling. I thought to myself, WOW how are they going to feed and maintain that tank. Well couple months later, that tank was on e-bay lol!
It's cool to see the art of the tanks and the guys are goofy so it's entertaining. Hope not too many fish suffer from this show. But they always start off with nice show piece healthy fish!
You also have to watch the episode where they build QT tanks for a person it was a think of beauty.
