I tried keeping them but it didn't work out for me, I had two of them one climb out of my tank and I found it about two months later when I was cleaning my closet. So I bought another one and try to keep with my puffer but as soon as he saw he try to eat it lol....so I took it out and kept it in my community tank but that didn't work either because the crayfish kept eating all the fish in the tank....he probably kill six or so
so I just gave it away to some guy on craigslist.
