GloFish Longfin Tetra Care Guide
Gymnocorymbus ternetzi var. GloFish Longfin · Freshwater Fish
What GloFish Longfin Tetra look like
This morph combines fluorescent GloFish coloration with the longfin form of Gymnocorymbus ternetzi. Fin length is longer than the standard tetra but the body remains that of a black skirt tetra.
Behavior & temperament
Care is the same as standard GloFish Tetras, but the longer fins make them slightly more vulnerable to fin-nipping. Keep a proper school, avoid aggressive barbs or fin-nippers, and provide open swimming space with plant cover.
Diet & feeding
GloFish Longfin Tetras are omnivores. Feed small flakes or pellets with daphnia, brine shrimp, bloodworms, and vegetable-based foods. Avoid only large hard foods that damage the mouth or foul the water.
Behind the name
Longfin describes the extended domestic fins; GloFish describes the fluorescent retail line.
Plan your tank
Check the numbers before you buy: tank volume, a stocking plan, cycle progress, water changes, and your ongoing care routine.
