like what?Your tank is probably full or almost full. If you were to add any more fish, it should probably be only one fish that doesn't need a group.
Well...I believe Gourami fish can go into 10 gallons and I believe that they don't need a school. And if you can put one in there, there are different kinds to choose from so it's up to you on what kind you want. I personally like the neon blue gouramis.
Well the petco that I go to have like lots of cories in a 10 gallon tank with gravel substrate.I am interested in getting cories too but Bronco told me that they do better with a sand substrate. Good thing he told me that before my cycle ends. Apparently the gravel can damage their skin.
okjust make sure you keep up on the pwc
