But the Synodontis Eupterus will be staying the 120Gal when i swop the fish about into the 300Gal .
Fry;2304623; said:Looks like your stock level is about right for a 300 gallon when the fish are full grown. I wouldn't add any more fish unless you perform more than a 50% water change a week or have an automatic drip system that changes the water with the same efficiency. Just my guess though, the reality will depend on your test readings of course.
