sh stands for snakehead. I don't recomend them either, for a community tank.
For a 1,000g tank (I assume you want a community tank of large fishes) I would definitely stock it with lots of south american pims, including tiger shovelnose cat, juruense cat, tigrinus cat, Platynematichthys notatus, and maybe even flavican cats.
There are tons of choices out there, all of the above (simply do a good search for pictures) will grow up to or over 2 feet.
