Yea, but why?!? I sometimes find myself at a crossroad between stop punishing poor fish and oh i want that in my salt water tank. you want to bring a fish to a completely different environment that involves a) multi day acclimation and b) stick this needle in his swimmy thing to let the pressure out so his insides don’t blow up to the outside...at what point do you draw the line?
Next question, what are you going to do with lighting for this guy? Photosynthesis stops around 600 feet, at 400 feet, photosynthesis happens, but not like it does on a reef. Meaning lighting is minimal at that depth. So what is this guy gonna do in a 2 foot reef tank? Might wanna throw some SPS 500 in there; maybe some aloe Vera too.
