I went to my LFS and they had one tiger that is about 2-3 in. I decided to put him alone in a 30 gal growout tank for awhile alone, I will post pics later didnt want him to end up as a snack lol
With regard to the caves and hiding places for the dats, I found that even though I had caves for my dats, that would stay out among the fronts anyway. I no longer have this combo but I do miss it. Good luck with yours.
