The Marbled Limpet Nerite Snail is a very unique and uncommon species that comes in a variety of great shell patterns!


The Marbled Limpet Nerite Snail (Septaria porcellana), also known as the Porcelain Limpet Nerite Snail, is a beautifully-marked, limpet-like gastropod that is very new to the freshwater aquarium world. Its shell is described as “tent-like” or similar to half of a clam’s shell. These snails are rather compact and small-bodied compared to snails of similar size, so they produce less waste and contribute less to the bio-load of the aquarium. The Marbled Limpet Nerite Snail LOVES the surface of glass and rocks and it can cling to those surfaces with unbelievable strength. Due to its strength and the protective shape of its shell, the Marbled Limpet Nerite Snail can often be kept in an aquarium with animals that are typically not compatible with most other snails and gastropods.

Unlike many limpets, the Marbled Limpet Nerite Snail is a highly herbivorous species that eats a great deal of algae and biofilm. It is native to freshwater, brackish, and marine tidal areas where it congregates with other snails and scours rocks, contributing heavily to preventing the overgrowth of algae. Though it sometimes originates from brackish and marine environments, the Marbled Limpet Nerite Snail is highly adaptable to fresh and brackish water. It is widely believed that it spawns in brackish or marine environments and spends the majority of the rest of its time in freshwater. Breeding in freshwater has been reported, but such reports are unsubstantiated thus far. We have kept the Marbled Limpet in our freshwater tanks for months to ensure its longevity, and it has thrived magnificently.

Care for the Marbled Limpet Nerite Snail is basic and undemanding.  It requires clean, mature water with the availability of plenty of algae and biofilm to thrive, but it will also usually eat high-quality dry foods. We recommend dosing GlasGarten Bacter AE for optimal algae and biofilm growth.The Marbled Limpet Nerite Snail's small size and low bio-load make it an excellent candidate for nano aquariums. 


We now offer B-grade Marbled Limpet Nerites as well.The B-grade variants mean that the snails may have minor shell damage, erosion, or calcification, but are otherwise perfectly healthy. Responsibly wild sourced snails do not always come in with perfect shells so we offer these at a discounted price to help find them good homes as well even though their shells are not in pristine condition.


* IMPORTANT NOTE:  Because of their unique shell shape, these snails have difficulty turning themselves when they have been overturned.  This is unlikely to be an issue once they are established in your aquarium, but take care not to place them on their backs when introducing them to your aquarium. *


What We Like About This Snail:
  • Completely peaceful
  • Highly variable, attractive color patterns of black, gray, white, and tan
  • Safe with all plants, but eats algae voraciously
  • Excellent scavenger that contributes a lower bio-load than most snails
  • Thrives in a variety of environments.
  • Temperature:  74° - 84° F (23.3° - 28.9° C). 
  • pH:  7.5 - 8.2, although some specimens will adapt to lower pH
  • KH:  2 - 12 dKH
  • Minimum tank size:  2 gallons per snail
  • Diet:  Scavenger that feeds continually.  Requires very little feeding in a well-established aquarium containing algae, biofilm, or decaying plant matter.  In less mature aquariums, high quality dry foods with high plant content can be sparingly fed daily.
  • Social behavior:  Peaceful
  • Origin:  Taiwan
  • Average adult size:  1 - 1.5 inches (2.5 - 3.8 cm)
  • Average purchase size:  .5 - 1 inch (1.3 - 2.5 cm)

This colorful tetra is a true aquarium hobby classic!

These little tetras are one of the more beautifully colored fish available in the freshwater aquarium hobby!  They have a silver body and feature a shimmering red/pink stripe throughout the middle of their body.  Their eye-catching coloration has made them one of the most popular fish for freshwater aquariums today.  They are great for beginners and experts alike, and they thrive in any well-established aquarium that meets their recommended water parameters.  These fish stay small, growing no larger than one to two inches, which makes them an excellent choice for small-sized tanks!

Glowlight Tetras are very peaceful and make great additions to community aquariums.  However, they should only be kept in tanks with other non-aggressive fish that are similar in size.  They are a schooling fish, and their schools create a magnificent display of colors in motion that has to be seen to be believed!  These fish do best in densely planted aquariums with plenty of hiding places.  This can be achieved with rocks and caves, driftwood, and live plants (good ones include mosses or tall plants that will reach the middle level of the aquarium, such as green cabomba, moneywort, java ferns, etc.).  Since they are a schooling fish, they can really only thrive in groups, which is why we sell them in groups of 6 and 12.

Glowlight Tetras spend most of their time within the middle and top levels of the aquarium.  These fish are not recommended for new tanks, as they may have problems in tanks that are not well-cycled.  It is important to acclimate Glowlight Tetras to a new tank slowly, because they can be sensitive to changes in water parameters.  They are known to be difficult to breed in captivity; the water conditions must be perfect for them to spawn.  Interestingly, the bright colors on these fish tend to become dimmer at night.  This is normal and does not indicate sickness or weakness in the tetras.

Shipping Schedule for this service

UPS 1 Day: Monday through Thursday

Current Handling Time:

1-9 business days

Here at Aquatic Arts, we consider the welfare of the live animals we are shipping to be of the foremost importance. This process is much more involved than simply creating a shipping label and affixing it to a box. Depending on the order, it takes from 4 to 7 people to complete this process properly. We check the weather conditions here where they fly out of the Indianapolis UPS facility and the destination for each shipment. We start early each morning and go through a multi-step process to have the day's shipments prepared in time for the UPS pickup. The volume of orders in our system also affects the processing time. Therefore our stated handling time is 1-9 business days. 

Shipping Rate

Pricing is by size of package needed to fill entire order and distance it must travel. It will be calculated at checkout.



Q: What are the ideal tank mates for Glowlight Tetras?
A: Glowlight Tetras do best with other small, peaceful fish. Ideal tank mates include Neon Tetras, Harlequin Rasboras, Corydoras Catfish, and small livebearers like Guppies or Mollies.

Q: How often should I feed Glowlight Tetras?
A: Glowlight Tetras should be fed 1-2 times a day. Provide only as much food as they can consume in 2-3 minutes to avoid overfeeding and water quality issues.

Q: What should I do if my Glowlight Tetras are not schooling?
A: Ensure you have at least 6-12 Glowlight Tetras, as they are schooling fish and feel more secure in larger groups. Also, check if there are any stressors in the tank such as aggressive tank mates or poor water quality.

Q: Can Glowlight Tetras live with shrimps and snails?
A: Yes, Glowlight Tetras are generally safe with non-aggressive invertebrates like shrimps and snails. They add a nice dynamic to the aquarium and help with cleaning.

Q: How can I tell the difference between male and female Glowlight Tetras?
A: Males are usually slimmer and may have more intense coloring, especially during breeding times. Females tend to be rounder and slightly larger, particularly when carrying eggs.

Q: What signs of illness should I watch for in Glowlight Tetras?
A: Watch for changes in color, fin rot, spots, or unusual swimming behavior. Common illnesses include ich, fin rot, and swim bladder issues. Quarantine affected fish and treat the tank if necessary.

Q: What lighting conditions do Glowlight Tetras prefer?
A: Glowlight Tetras thrive in subdued lighting conditions, which mimic their natural habitat. Moderate lighting with plenty of plants for shade creates an ideal environment for them.
