i just got a single baby peacock bass from one of my local pet stores im not sure which kind he is but i will when he is older and yes i know how big they get at adult size could he live in a 150 or if not maybe 180 or 200 150 is better for me though im just courious he is in a 10 gallon for now and then possibly to a 55 if i do not have the bigger tank by than he is also liveing with 2 dalmation lyre tail mollies and a stripped raphel catfish
