Hey Aquarists! š
Ever felt like your desk, nightstand, or dorm room was missing somethingā¦ alive?
A 3-gallon aquarium is the PERFECT solution
Tiny but mighty.
Packed with personality.
And oh-so-satisfying to stare at!
Today, weāre diving into 12 insanely cool freshwater setups for your nano tank.
If you're vibing with any of these, check out our Facebook group for inspo! Link at the bottom.
š„ #1: The Betta Paradise
One glamorous Betta fish
Why It Works: Bettas are low-key divas who love their personal space. A 3-gallon tank is their mini palaceāadd silk/live plants (Java fern, Anubias) and a tiny cave for maximum drama.
š” Pro Tip: Use a gentle filterāBettas hate strong currents (theyāre not into cardio).
š¦ #2: Shrimp Party Tank
6-8 Cherry Shrimp (neon colors = instant vibes)
Why It Works: Shrimp are the ultimate tiny tank cleanersātheyāll graze on algae and look adorable doing it. Add Java moss for their snack-and-hide needs.
š Bonus: Shrimp breed easilyāsoon, youāll have a whole shrimp dynasty!
Only about 4% of U.S. pet owners have pet insurance
Pet care costs are rising, yet not enough people are doing something about it. Pet insurance can significantly offset rising costs ā all for as low as $10 a month. Want to join the 4% club?
šæ #3: Nano Aquascape (Mini Jungle Vibes)
Dwarf Hairgrass + tiny driftwood
Why It Works: Itās like a bonsai gardenā¦ but underwater. Keep it simple with 1-2 shrimp or snails so the plants steal the show.
šø Insta-Worthy: Perfect for those āLook at my tiny zen worldā posts.
šØ #4: Endlerās Livebearer Trio
3-4 male Endlerās (all colors, no babies!)
Why It Works: These guys are living rainbows and love zipping around. Float some plants to keep them comfy.
ā ļø Warning: Females = baby explosion. Stick to males unless you want a full-time fish daycare.
š” #5: Marimo Moss Ball Zen Zone
3-5 fuzzy Marimo balls + 1 snail
Why It Works: Zero effort. ZERO. These little green orbs purify water and thrive on neglect.
š§ Vibe Check: Add smooth stonesāinstant ASMR tank.

2-3 Mystery/Nerite Snails

šļø #7: Micro Aquatic Garden
Duckweed + Anubias Nana Petite
