💙 Cosmic Tetra (Gymnocorymbus ternetzi)
 
Add bold color and movement to your freshwater tank with the Cosmic Tetra — a visually striking, dyed variant of the classic White Skirt Tetra. Known for its shimmering blue hue and peaceful schooling nature, this fish is a popular choice among aquarists seeking vibrant display fish for community setups.
While these fish exhibit a stunning appearance, it’s important to note that the coloration is achieved through a dyeing process. As such, they may require gentler care and tend to have a slightly reduced lifespan compared to naturally colored or genetically enhanced variants.
 
✅ Key Features:
Peaceful, active schooling fish
Ideal for community tanks with other gentle fish
Captive-bred and ethically sourced (note: color-enhanced by dyeing)
Recommended for aquarists who understand the nature of dyed fish
 
⚠️ Note on Coloration:
These fish are color-enhanced using artificial dyes, a method that is not permanent. Over time, their color may fade, and dyed fish may be more sensitive to stress and disease. We encourage responsible fishkeeping and always recommend choosing healthy, captive-bred stock from trusted sources.
