Hey guys i use to have 2 rbp's 1 year ago that were only about 4 inches long or so but something came up and i had to take down my tank for a while so I gave them to my friend...He has had tht RBP's in a 29 gal for about 1 year now and are the same size as when I gave them to him...But now I have a 60 gal ready to go and my buddy is giving them back to me...SO my question is, Are the piranha's stunted? Or will they get a little bigger in my new 60 gallon..They have never expeirienced a tank bigger then 29 gal so I know they will be living it up!This tank is also a wide and tall not long so I feel like they will have alot of potential growth.
