I have recently bought 25 gal tank and I was thinking about setting it up for an angel fish. I am not sure what way to go with setting the tank up to make it simulate the amazon waters that they originate. I was told to put peat moss under my gravel to help get the ph at a good level and it will also give that tea color affect to the water also I was told to pout in a floating plats. Does anyone have any suggestions or thoughts on what why I should set up this tank????
