How big can my Rosy Red get and...

Would a Koi eat him .

I know this sounds funny, but I got a Rosy as a feeder fish , and he was never eaten so I have grown to like him , and I want him to get big and healthy. So I was wondering if I moved him into a tank with a Koi would be eaten than ? And like the title ask how big can he get.

They get about 3 inches. When we started our 55g we used them for cycling (yea yea boo I know) Once the tank finished we kept them in there we when started stocking. Eventually the tank was stocked up to 2 jewel cichlids, 2 firemouths, 2 jack dempseys, 3 pictus and a pleco. Those 2 dozen roseys fought off the cichlids for the flower pot caves!
