well to me the 2 fish they shouldnt sell are the pacu and now the ck. Ck's arent real easy to get in albany even thought they arent pricey. I bought my ck because u dont see them all the time here. But to make it worse the tag said it needs a 175 gallon tank which would be ok for a ck if it stops growing at 18 inches but the girl working there said that the slip isnt minimum size. she said i could get away with a 75-90 gallon. I said i dont know about that. I told her i had one and that he's in a 75 and i have a 150 for when hes bigger but i was also saving a 250+ gallon tank for the future. She said well they dont need that big. I said that there are many ck's in tanks that are almost 3 feet but thats rare. She said thanks for the info, i told her to explain that when ppl wanted to buy one
