I have three spotted cories (Corydoras melanistius) in a 30 gallon tank with one balloon molly and her two month old fry. I want to buy at least 2 more of the same cories, however I'm not sure it's completely neccessary.
The three are constantly following eachother (two in particular) all around the tank. Once in awhile the two will seperate from the other while it swims along the bottom.
These guys do not stay at the bottom forever at all. They wander all over the place.
So I'm wondering, should I add more cories or leave them be for now?
*note- there's no salt in the water except maybe a teensy bit I added to ward of diseases awhile ago.*
