So I am hoping to add a mandarin to my 20 gallon display. I would be adding it in a few months so i can prepare and raise enough food. I will be adding more live rock btw. So I was wondering, is a HOB refugium a good idea for raising copepods? I don't have enough space for a completely seperate setup. Would it work for keeping a mandarin in the long run? Thanks @ReefSquad
