CAYLAVIEWS: Penn Plax South Castle Aquarium Décor Full Detail
To put as a grouping (the left side castle), you will need at least a 50 gallon tank OR 30 gallon tank with smaller fish. The reason for 4 stars, rather than 5: I had already purchased the right side castle prior to buying this one. Purchased this item at Pet Co and love it. We have a 29 gallon tank and it takes up the entire right side. Looks great with black rock or tan color, as it makes the castle really pop.
