Ruby Tetra

The Ruby Tetra is an absolute stunning nano fish with hints of reddish orange color. They truly stand out in a planted aquarium. It is important to provide hiding places for these fish as they can get stressed out. We recommend rock and driftwood to create caves and crevices.

Please Note: All fish shipments have a 100% Live Arrival Guarantee when shipping with Overnight (1 Day) option. All other options void our Live Arrival Guarantee for fish. 

The Ruby Tetra will reach sizes of about 1 inch. They are pretty peaceful. Although, we would not recommend keeping them with shrimp. They prefer small live foods so baby shrimp would become an easy target. 

The scientific name for the Ruby Tetra is Axelrodia riesei.

We feed our Ruby Tetras a mix of frozen foods including daphnia, baby brine and cyclops. We occasionally feed them Northfin Veggie.

Healthy little guys

All 4 of my ruby tetras arrived quickly, safe, healthy, and happy. I tried to buy 6 but there were only 4 available. They are schooling with my ember tetras. They were packaged well for their travels. I would definitely recommend Flip Aquatics

Tough Little Guys

These ruby tetra have a really neat color vs your standard ember tetra. We love their shiny little tail spots. Also, they are resilient against new tank syndrome. Ordered a school of 14 and every single one survived ten days above 3 ppm ammonia along with daily water changes.

Ruby Tetras

The tetras arrived a day late because of a delay with UPS and unfortunately, one of the tetras was dead on arrival, but there were six total, so I did get five healthy little tetras! They were quite spooked at first but I followed the directions and they’ve acclimated quite well and like to hang out with my ember tetras in the tank. They’re eating well and gaining their color back, overall I’m very pleased with my purchase and will definitely be buying from flip aquatics again!

Beautiful shy fish

Beautiful nano fish. Perfect for a cave scape. They sit still more than the other fish and you really get a good look at them. They are a little shy.

Very happy with the delivery. Fish and snails arrived perfectly. I like the fact that you ship the snails in water. Less stress on them.

My first experience with the breather bags...very interesting.

The Ruby tetras are so tiny and cute. They are getting along very well with my Embers.

Thank you!
I will definitely order from you guys again...Mary K
