Choose how you want to shop
Start with the category that matches your tank
These entry points make it easier to shop for peaceful nano fish, cleanup helpers, and starter bundles without digging through the full catalog.
Shop by tank size
Match the fish to the tank you already have
Choose the 5–10 gallon view for lighter stocking and smaller groups, or the 10–20 gallon view when you have room for fuller schools and more bottom activity.
Some of the same peaceful fish appear in more than one category because they genuinely fit both beginner and tank-size shopping.
Browse by setup style
Choose planted fish, cleanup helpers, or a starter bundle
Use these categories when you already know you want planted compatibility, cleanup help, or a starter bundle instead of building the whole order one fish at a time.
This is the clearest first stop when you already know you want planted compatibility, gentler cleanup help, or a bundle built around a specific nano goal.

What does overnight mean for live fish?
Overnight refers to transit speed after the order ships. Processing usually takes 3–5 business days before shipment.
Why do you ship Monday through Wednesday only?
Shipping early in the week helps reduce weekend delay risk and keeps live fish safer in transit.
What should beginners buy first?
Start with calmer species, smaller groups, and compatible cleanup helpers that match your tank size. Beginner Nano Fish and Best Sellers are the easiest places to start.
How do bundle substitutions work?
Bundles are built around a target mix for a specific small-tank goal. If one listed item is temporarily unavailable, a healthy comparable substitute may be used to keep the setup balanced unless the bundle is marked exact-species only.
