Accessories
Seachem Prime Water Conditioner
The essential dechlorinator and detoxifier for every tap-water aquarium. A single small dose immediately neutralizes chlorine, chloramine, and temporarily detoxifies ammonia and nitrite. Neon Tetras are sensitive to poor water quality — Prime is non-negotiable for every water change.
Filters
Fluval AquaClear 20 Power Filter
A quiet, reliable hang-on-back filter rated for tanks up to 20 gallons — the right size for a Neon Tetra school. Its multi-chamber design provides mechanical, chemical, and biological filtration with adjustable flow, preventing the strong current that can stress small fish.
Food
TetraMin Tropical Flakes
The classic community fish staple. These vitamin-enriched flakes are perfectly sized for Neon Tetra mouths and float briefly before slowly sinking to match their mid-water feeding behavior. Color-enhancing ingredients help maintain their vivid blue and red iridescence.
Hikari Tropical Micro Pellets
Semi-floating micro pellets sized for the tiny mouths of Neon Tetras. The slow-sinking action suits their natural mid-water feeding, and the formula includes color enhancers that intensify the electric blue stripe Neon Tetras are famous for.
