Care Guide for Ember Tetras – Orange Jewels of the Nano Aquarium
The ember tetra is a staple in the freshwater nano-aquarium world. Just imagine a school of tiny, flame-colored fish darting back and forth amongst a lush forest of green aquarium plants. Plus, its peaceful nature and hardiness makes it an attractive choice for both beginners and veterans in the fishkeeping hobby. If you’ve never tried keeping ember tetras before, then keep reading to find out why they’re such a top-selling species at our fish store.
What are Ember Tetras, you ask?
Hyphessobrycon Amandae, a common tetra that is found in Brazil, comes from the same genera as other well-known tetras such as Von Rio tetras and the black neon Tetra. Although this species is only 0.8 inches (2 cm) in length, it packs a punch with its bright red-orange body with a slight translucent sheen and coppery sheen. Unlike many other nano fish, ember tetras are relatively outgoing, especially in large groups, and won’t dart away as soon as you approach their tank.

How to set up an aquarium with Ember Tetras
Due to their small size, they can be kept in a 5-gallon Nano tank with a smaller school or larger tank with a large group. They come from mildly acidic waters but are adaptable enough to handle pH of 5.5-7.5, 72-82degF (22-28degC), and very soft to moderately hard water. A sponge filter sponge or pre-filter sponge can be used to gently filter the water. Slow flow is preferred. We find that ember tetras tend to show brighter colors in planted tanks with a dark substrate and background. Hobbyists like to add driftwood, catappa leaves and other interesting botanicals to give their tanks a South American look.
How many ember Tetras should I keep? They are social creatures and feel most at home when they are surrounded by their species. They are not a tight-knit group, but rather prefer to live in a loose group or small shoal. We like to have at least 6-10 of these tiny fish so that they can make an impact in the aquarium.
What fish can live with ember tetras? They are the perfect community fish and do fine with any similar-sized, peaceful animals that won’t eat them. For example, you can keep them with other nano schooling fish such as rasboras, tetras, and danios. Since they tend to swim around the middle of the aquarium, we like to pair them with bottom-dwelling corydoras catfish and surface-dwelling hatchetfish or pencilfish. Plus, their gregarious nature makes them well-suited as dither fish for Apistogramma dwarf cichlids or other timid creatures. We also find they get along with algae eaters like otocinclus catfish and dwarf shrimp. While they will leave the adult shrimp alone, almost all fish will opportunistically go after baby shrimp, so provide plenty of dense plants and caves for them to hide.
Can I put a betta fish with ember tetras? A blue betta fish or powder blue dwarf gourami would look amazing as a centerpiece fish among a sea of ember tetras because blue and orange are complementary colors. Be aware that some dwarf gouramis or bettas are territorial and may need to be moved if they get too aggressive.

What do Ember Tetras Eat?
They are omnivores and eat zooplankton as well as small invertebrates and plant matter. While ember tetras are not picky eaters, they do have little mouths that prefer to feed on tiny, slow-sinking foods. Plus, feeding a varied diet of different fish foods will help them get plenty of essential nutrients and vitamins to live a long and healthy life. Our favorite foods include:
Nano pellets Crushed flakes Baby brine shrimp Easy Fry and Small Fish Food Daphnia – Cyclops – Rotifers
How to Breed Ember Tetras
It can be hard to sex ember tetras, so we recommend buying at least six fish to have a higher chance of getting both males and females. Males are slimmer in profile than females. Females have rounder bodies when viewed from above. Because they are egg scatterers, they don’t need to be supervised and will prey on their eggs and the newborn fry. However, ember Tetras can be raised in a colony where parents and the young are kept together. You need to provide them with plenty of microfauna to feed the fry and dense plants such as Pogostemon Stellatus ‘octopus” and water sprite for them to hide in.

For greater yields, use a mature, small tank that has a sponge filter. Place java moss or DIY spawning mop as shelter underneath the plastic mesh that covers the tank’s bottom. The barrier prevents the eggs from falling through the holes and keeps the adults away. To make biofilm, add some catappa leaves to the soil. If your pH is higher, you can also acidify the water by adding them to the water. After feeding and conditioning the adults to spawn, you can transfer them to your breeding aquarium. After several days of spawning, remove the adult fish and fry if possible.
Tiny babies need tiny foods like infusoria and vinegar eels. Keep them fed small meals at least once a day. Also, make sure you change your water daily to maintain a stable water quality. You may be able for them to start eating baby salt shrimp after a few weeks depending on their water temperature. This will increase their survival rate and growth. If you see a great disparity in the sizes of the baby fish, you may need to move the bigger fry to another grow-out tank so the smaller fry won’t get outcompeted for food.
