Some of those shouldn't even be considered for shipping... i dont care the color or no matter how nice how big..
If that Kok isn't as on par with #4 its not saleable..
I once brought in a FH with a kok about the size of #1 and #3 and the dam store owner rejected it saying that its no good and crap.. (basically they were trying to make money off it by saying its no good so that i would just give them the fish free) but my FH was a ZZ malau.. anyways..
Trust the 5 other people who agree with me go with #4! the Kok takes a longggg time to grow.. and even with sumo.. takes many many months..
