A lot of people think they are really lazy. I found that those people never had one and going by what others told them. As a shark goes, yes, they are inactive. But as a fish goes, they are about the same.
yeah i know. Im was thinking if it is immune to ich why not put it in but know that i really think about it it wouldnt be a good idea. it would probly hurt the other fish with the extra bioload while they're sick right?
No, it will surely kill it. Now you need to find a new home for the shark. The trace copper elements on the LR and in the LS are enough to do damage. Even the amount absorbed in the silicone on the side of the tank and in the filtration is enough to throw it "off-feed". Time to trade him in or find a home.
Yeah, that would be fine for up to almost 2 years from my experience with them. Just make sure that the tank is still OK to be used and that the bacteria are still thriving if there has been no fish in it for a while.
