What is the average size of a German Blue Ram fish? Is 5 German Blue Ram fish enough in a 5-gallon aquarium?
German Blue Rams usually have a tank length of 5 gallons. However, a 5-gallon tank is not enough for 5 fish; you should use a 20-gallon tank.
It seems like the 5-gallon size is not big enough; you should use a 20-gallon tank.
