I have a Texas pair and their growth have slowed drastically since they started breeding in my 125. I wanna separate them so can gain some size and then introduce her back into the 125. I know a 100 gallon will be more than enough for her but I don't want her to live alone. So I was thinking if a 100 gallon is suitable for her, a female festae and perhaps a female trimac? Keep in mind that once she reaches about 6-8 inches she'll be back into the 125 so the female festae and trimac will have it all to them selves.
