Lol looks like my info is wrong about how big they got, my memory is betraying me I guess haha. They do get the same size as silvers apparently... I read they only get a bit larger than two feet somewhere before...
3 Ft in the wild. upto 30" in the aquarium. COngrats on the growout black! I have yet to have good luck with a baby black. After 5" they are a breeze to care for. just cover every hole no matter how small it is, or the fish might jump out. my old 17" black jumped through a 2" hole and died..rookie mistake but never thought the fish would jump through it!
