I voted for Sterbai, just because I like their coloring the best. They also tolerant warmer temperatures quite well. Don't know how warm your tank is, but that could be a consideration.
+1 on the sterbai. I have 12 in my 37 gallon pool filter sand tank. They have the best coloration and are fun to watch. Also, they aren't that picky as far as tank temperature. Once acclimated, they tolerate a lot.I voted for Sterbai, just because I like their coloring the best. They also tolerant warmer temperatures quite well.
