a dead koi that i put in my moms flower beds. the damn corpse ended up giving my moms flowers root-rot. but it really wasnt a bad buy when i think about it. 2 bucks for a 15 inch dead koi.
Lets see i bought a Cowfish,Electric Catfish,Tire track eel all of wich hardly ever moved.I bought a foot long Buttakaforia for 5 bucks only to have it bite me TWICE!!Any Pacu i have ever bought,and the list goes on.The lesson learned never go fish shopping with your wife(especially if she wants to save every cute little fishy she see's)DAMN!!!
i bought 5 blue rams at a small size to get them to breed,they had not much colour so naturally i figured out of 5 i would of got at least one female,i ended up with 5 males at 14$ a pop
