They are in a 90g for now and should be able to stay there for a good long while (hopefuly). They way this tank is set up there are many hiding places and tons of room to be out in the open yet out of line of sight of each other so no problems yet.
Like I said I have no intention of breeding them, we actualy had the female first, my girlfreind has always wanted a big male and when we found out that we had a female she was dissapointed so we bought the male. Even though it is not a fish she originaly wanted there is no way she will get rid of the female now, so I guess we will just have to see what happens.
