So my plan for this tank was always to have a group of small gobies, for this size (it's a standard 10), would there be any problems if I kept a Trimma sp. and a Eviota sp. together? My main concern is because it is only a 10 gallon, the two species would fight over territory. Specifically, I'm looking at 3 Trimma Cana and 3 Eviota prasites or Eviota queenslandica from Biota. Any thoughts or concerns? I'd happily only do 1 species if they work out, I just thought that having these 2 together would be a cool contrast for something like a 10 Gallon.
