What fish should I get for my tank

Yes I check the water parameters regulary. They are all fine. I don't mean to sound mean, but you don't know what my cory catfish do. They are very active and I can test it because my fiance has a ten gallon with 4 cory catfish and mine are more active then his. I have done this for 3 years now and on another post of mine, people told me that it would be fine. But I appreciate your concern
mmmm.... then all sounds well, despite the somewhat anomalic circumstances. however.... it would be wise that you not add any more fish IMO. wouldnt want to disrupt the current equlibrium.
 
I think your tank already has the right stocking level. I wouldn't add anything to it.
