I have an iridescent shark I have acquired, or inherited, or whatever you want to call it. I subleased an apartment and now I have a fish that is too big for it's tank, the original owners didn't take it with them and I don't think they really knew what they had bought. So if there is anyone the NYC/New Jersey area that would like to give an ID shark a better home, drop me a note. This fish may not be in the best of health, but it's a survivor, no doubt. It's about 11" long now.
