Currently working on stocking a 29 gal tank. Currently have a few (5) Serpae Tetras in a 6.8 gal, and a few (9) Emerald Dwarf Rasboras on the way. Was planning on starting with the Rasboras and after they get acclimated, moving the Serpaes over. How concerned should I be about the Serpaes getting aggressive toward them if I do move them over? The 29 gal has light plant cover, a few rocks, and a few decorations but is open for the most part if that makes a difference.
