Captive Care: The PJ Cardinalfish has to be one of the greatest shoaling fish in the marine aquarium hobby for peaceful tanks. Not only is it a beautiful individual fish with its fun orange polka-dots but even more so to watch the shoal swim slowly in and through a reef. Keeping these fish in small groups is highly recommended in tanks larger than 30 Gallons. These guys are great for nano tanks as well since they don’t need a lot of space. Peaceful tank mates are a must, as in nature they do tend to hide in the tall grasses and plants.
