So while I try to add some color to my tank
I also notice I have a diamond tetra all by himself
A cory cat (not sure what kind) with no friends
And a loner swordtail
Is it a good idea to get some more of those fish into my tank?
Or is there a chance even with more of the same types they wont make new friends by isolated for as long as they have
The tank is 30 gallons and lots of room
