PLZ READ EVERYONE BEFORE POSTING AGAIN!!!
this is a grow out tank for the clown knife and the id shark(which will go in a larger tank when they are larger and i haven't seen an iridescent shark over 18" in my life, so...).in some of the books i have say chinese hi fins get only 24"...just an idea to see what everyone would say. AND the banded sharks can live in tropical conditions, but they will not thrive in them.
