PLEASE NOTE: This species will prey upon other small invertebrates and fish that inhabit the same areas of the aquarium. This species should not be kept with dwarf shrimp, most snails, and slow-moving or bottom-dwelling fish. It is an opportunistic omnivore and it will eat anything that it can catch.

The Giant Freshwater Prawn is an attractively-marked speciese that grows to an impressive size, especially for a freshwater invertebrate!

The Giant Freshwater Prawn (Macrobrachium spinipes) is a large Macrobrachium species that is very uncommon in the aquarium hobby. While Macrobrachium species are not considered true prawns, the "prawn" name is widely used due to their many similarities to true prawns. They are not quite shrimp, but not quite crayfish, yet they have many similarities to both. This species has noticeably long claws, and males have even longer claws than females. This particular species is amphidromous, meaning that it spends the early larval stages of its life in brackish or saltwater, then migrates to freshwater for its adult life.

Giant Freshwater Prawn is considerably more aggressive and territorial than freshwater shrimp. It is more comparable in personality to most crayfish. Adult males are territorial with other males and should not be kept together in a small tank. Males are reportedly much less aggressive toward females, and a pair can sometimes be kept together with caution in a tank of considerable size as long as ample cover is provided. The Giant Freshwater Prawn will do some digging and excavating in in its habitat, so delicate plants should be avoided. However, this omnivore can possibly be kept with more durable, well-established plants such as AnubiasCryptocoryne, and Java Fern...although there is no guarantee that it will not damage or destroy them. This species is somewhat adaptable regarding water parameters, but it will not do well in soft or excessively warm water. Like crayfish, will sometimes prey on fish and other invertebrates that inhabit the same areas of the water column. It can sometimes be kept successfully with agile fish that inhabit other areas of the tank, but it is a very effective hunter and can cause major damage or even death to its tankmates, especially in a relatively small aquarium.

The Giant Freshwater Prawn is an opportunistic omnivore. It is not a picky eater, and it should be offered a varied diet of dry, frozen, and live foods that contain both animal and vegetable matter. It will spend most of its time foraging around its chosen territory at the bottom of the aquarium.

Our B-Grade option for this species is simply for specimens that are missing a claw or multiple legs. This is completely normal for a crustacean and the missing appendage(s) will grow back within 1-2 molts.

  • Diet: Omnivorous. Requires a varied diet of animal and plant matter. Most dry, frozen, and live foods will be accepted, as will most vegetable matter
  • Social behavior: Can be aggressive/territorial with its own kind as well as other animals. Prawns will typically eat whatever they can catch, but since they are slow-moving, they are not often able to harm fast-moving fish that inhabit other areas of the aquarium.

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.

What We Like About This Fish:

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.
