finally someone agreeds. As long as ur water perimeter is good, clear water and healthy. They should do fine. The only draw back is stunted growth. Just like how i stated in my email. It not a "required" to buy a big tank. If u grow it from fry to large then it okay.
But if u buy it big big from lfs store, then that a different story. That all i am saying. They will grow base on living space. Do ur experientment and u see if i am wrong.
Example: small oscar in 10g, will not grow as big as an oscar in a 150?
