In 2017, it was discovered that Atlantic Sea Nettles were actually two distinct species. And so the Bay Nettle became recognized! What does this mean for us as jellyfish keepers? Bay Nettles are the species we currently aquaculture. They're also smaller than true Atlantic Nettles, and come in a wide variety of colors and patterns. They're the perfect nettle for the home aquarium. We try to stay as scientifically up to date as possible and will be referring to these as Bay Nettles from here on!
Bay Nettles are a beautiful jellyfish, found in Brackish rivers along the Atlantic Coast. These nettles come in a wide variety of colors. Their bodies are mainly white and they may develop red or brown spots, stripes and colorations. Keeping them at lower salinities will encourage these characteristic patterns. Keeping them at higher salinities often leads to bright white jellies. Bay Nettles have long and graceful tentacles that trail along with the jellyfish.
If Moon Jellyfish don’t suit you, Bay Nettles make an excellent beginner jellyfish. They are very hardy, and forgiving of mistakes. Smaller than their Pacific relatives, they get about 5" in diameter at max. Much like most other jellyfish, they will grow to meet the confines of their aquarium, meaning they can be kept in smaller tanks.
