Are your shrimp disappearing overnight or fish hiding all day in your nano tank? Most disasters begin with bad stocking choices. Let’s fix that with five peaceful, beginner-safe combos that actually work in 5–10 gallon setups.
🐠 Why Stocking Smart Matters
Nano tanks are tiny ecosystems—compatibility and balance here are more sensitive than in larger tanks. Studies show interspecies aggression in small tanks can spike without proper environmental enrichment and crowd control.

🥇 Top 5 Peaceful Nano Combos
#5 • Chili Rasboras + Pygmy Corydoras
Tiny, colorful chili rasboras (Boraras spp.) are shrimp-safe, schooling fish with gentle behavior. Pair them with miniature pygmy Corydoras to add bottom activity without conflict.
#4 • Celestial Pearl Danios + Amano Shrimp
Celestial Pearl Danios are calm schoolers; Amano shrimp help control algae. They coexist beautifully without stress—perfect for planted nano tanks.
#3 • Honey Gourami + Ember Tetras
Honey Gouramis bring soft pastel color and mellow temperament. Add a small school of Ember Tetras for contrast. Combine with Nerite snails for balance.
#2 • Endler’s Livebearers + Nerite Snails
Endler’s are hardy, always active, and non-aggressive to shrimp or snails. Nerite snails clean substrate and plants without harming tankmates.
#1 • Sparkling Gourami + Cherry Shrimp
Sparkling Gourami are peaceful, surface-dwelling fish that rarely harass shrimp. Pair them with cherry shrimp for a stunning nano display.
🌱 Bonus Tip: Plant First, Stock Second
Heavily planted tanks help create hiding spots, reduce aggression, and improve water quality. Always plant before adding livestock—fish feel safer, bacteria stabilize quicker, and your tank blooms in harmony.
