Cubaris “Penguin” is a charming, slower-breeding isopod species that’s ideal for keepers who enjoy patience and attention to detail. With their smooth black-grey colouring and rounded “penguin-like” shape, these little guys add a sleek, elegant touch to any bioactive setup. Unlike more common species, Penguins are a bit shy and tend to stay tucked away — but when they do come out, they’re a joy to watch. They prefer stable, high-humidity conditions and a moisture gradient in their enclosure.
