Hey guys... I was thinking about getting a bigger tank. Currently I have a 75 with one 5-6 inch red belly. I was thinking about getting two or three more of the same size. But at 10 or 12 inches when fully grown they will look way to big for the tank in my opinion. So how long will they take to go from 5 to 12 inches? I think they would look awesome in a 125 gallon! Thanks for the help!

They keep growing rapidly until the reach 5-7" in length (within 8-10 months, depending on many factors like water quality, diet, tank size etc.). After that, their growth slows down noticably.

Most people will not be able to grow Natts to 12" for some reason, but I have friends that have searched all resources and they just arent out there in the US and Canada at least.

If you did have a fish that had the possiblilty for that size you are looking at least 5 years more like 7 or 8 though

Yeah they rarely get to be 12 inches, a 75 gallon should be fine to house like 3-4 reds for a long while if not for life.
