Well just a tank large enough to qualify (8ft plus?) When i have my own houseI would say so, I mean by larger tank, how big we talking? TBH tigerfish r not that difficult to take care off. Clean water n big tank n ur good. Goliaths r beasts, but go with TATF or VATF they get smaller n I think look better. They wont have that real beast look, but I think they have better colors
