I plan to start a NPT using Petco's 6.6 gal Bookshelf aquarium (8.13" L X 24" W X 9.25" H).
Is the tank big enough to house a betta and 3-4 cories? I read that cories do best in groups of 6 or more, but I also read that juliis do fine in groups of 3-4. My Petco sells albinos and juliis while Petsmart also has emeralds and pandas (I like the panda ones the best). However, neither have pygmies which I heard do well in the 6.6.
If yes, which cory do you recommend? If not, then I think I can settle with a few ghost shrimp and algae eater. (While I'm at it, does anyone know any good substrate aerators beside MTS?)
