Aquarium Advice Regular
OK. I have a 20 gallon reef tank and I want to know how many fish I can put in it. I just plan to put blue damsels, and I want to put as much as I possibly can. How much blue damsels can I put in? If I add an extra CPR refugium, will that allow me to add one more damsel? Thanks to anyone who can reply to topic!
