Im planning a stocking list for my 6x3x1.2 foot aquarium but I would like to have multiple fish that love to eat cope pods. 1 finger dragonet, 1 yellow tail tamarin, 1 black spot leopard wrasse and a adorned halichoeres wrasse. My refugium will be around 30 gallons when full with water and im wondering if this will be too small to provide the necessary critters for these fish. Any help appreciated thanks
