The Glowlight Tetra glows like a lamp when lighting conditions are just right. The colorful, neon red/orange stripe shows up best when the aquarium lights are dimmed. For maximum visual effect keep Glowlight Tetras in groups.

The Glowlight Tetra is a very popular and hardy freshwater tetra. It originally came from the clear water streams of South America. This fish has a clear body with the exception of its signature bright neon red stripe running from the nose into the tail. Glowlight Tetras are a great addition to any soft water community aquarium.

Glowlight Tetras add beauty to a planted aquarium; the plants, in turn, will provide hiding places for the fish. Rocks and driftwood also help to mirror its natural habitat. It thrives in slightly acidic water and will do best when water parameters are kept constant. The Glowlight Tetras are a schooling fish and are very interesting to watch in action when kept in odd numbers of five or more.

To breed Glowlight Tetras, separate a pair into a "breeder tank" with no lighting at first, and then gradually increase it until spawning occurs. Water hardness should be less than 4 dKH and live food such as mosquito larvae are great inducers. Be sure to remove the adults after the eggs have been laid, as they will eat them. The eggs should hatch within 30 hours.

Glowlight Tetras will accept many small foods such as brine shrimp or daphnia, freeze-dried bloodworms and tubifex, micro pellet food, and a high quality ACflake food.

Approximate Purchase Size: Small: 1/4" to 1-1/4"

Customer Testimonials

Farfel M Linden , MI
These are perfect tetras! These are so hardy! I love mine!
Jason B Bayonne , NJ
It seems that these species do very well with different species that are the same size. I have noticed this in my 55 gallon tank. I house them with similiar size neon tetras and cardinal tetras. They school slowly in the lower strata and do not fight each other as I have seen with the medium to larger size tetras.
Katie T Cincinnati , OH
These tetras are great! They're very hardy and fun to watch. Beautiful, too. Thinking of converting my 'fake' aquarium into a planted one - we'll see how these fish do!
Dan B Tampa , FL
These are the best small-tank fish in the world! They are extremely active. Buy them.
Alek B New Orleans , LA
This species of Tetras are so awesome! They get along with the rest of my fish really well. I Love Them!!!
Eric C Nashville , TN
Great fish, schools are looser if they are comfortable. They LOVE to hang out just above shorter plants in a tank and tend for flake food to drift down to them rather than go up after it.
Nicole T Wichita , KS
I love these fish! All of them arrived alive and healthy. I look forward to my next purchase.
