This blue eye dwarf rainbowfish species is a beautiful, outgoing, hardy, and all-around superb addition to the nano or planted aquarium! The Aru II variety displays an especially striking coloration.

The Aru II Gertrude’s Spotted Blue Eye Rainbowfish, (Pseudomugil gertrudae) is a high end, rare variant of the Gertrude's Rainbowfish and is native to Indonesia, New Guiniea, and Australia.  It lives in very large schools in areas with dense vegetation, so it is an ideal candidate for the planted aquarium and especially enjoys the cover of floating plants. Juveniles start out with a mostly silver body, but develop into a truly striking coloration. Males display a turquoise blue/silver on their bodies and fins while keeping the yellow head of a common Gertrude's Rainbow. The second dorsal and anal fins of males  become very extended and fan-like with maturity.  Females are typically smaller and often possess an attractive orange-yellow hue. 

The Aru II Gertrude’s Spotted Blue Eye Rainbowfish is peaceful with other fish species of similar size and can even be kept with adult dwarf shrimp.  The most intense color will be displayed when this fish is kept in schools of 6 or more, including multiple males, in a heavily planted, spacious aquarium to ensure that subdominant males are not overly harassed by dominant males.  As with many rainbowfish, darker substrate will also often result in better coloration. 

While this fish will easily accept high quality flake foods, it should also be fed plenty of small frozen or live meaty foods for optimal health and coloration.  The Gertrude’s Spotted Blue Eye Rainbowfish is a timid fish, so it can easily be out-competed for food by more aggressive eaters, so care must be taken to ensure that it gets its share of food.

The entire family of rainbowfish is popular in freshwater aquaria due to the generally peaceful disposition, hardiness, and beautiful coloration of its members.  While many popular rainbowfish species eventually become too large to be kept with dwarf shrimp and some other nano species, the Gertrude’s Spotted Blue Eye Rainbowfish is one of a few exceptions.  Fully grown rainbowfish of this species are typically safe to keep even with adult dwarf shrimp and virtually all non-aggressive invertebrates that we offer.

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.

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.
