I am pretty alright with freshwater fish, but, that is mostly when it comes to Danios, Mollies, Guppies, and yeah... I am thinking about getting about 3 African Chilids in a 20 gl. tank I have, But... I like things Vivid so I would really like it if someone can help me figure out fish that may get along... Some fish I had in mind was Shar fish (red-tail shark or bala shark) and a Osar(sp) Help anyone?
