How to Choose

What to Look For

Prioritize compatibility first: tank volume, filtration capacity, water chemistry, and temperament must align with your livestock. Buy a test kit and use it weekly during the first month — ammonia and nitrite spikes are easier to fix early. For livestock, quarantine when possible and acclimate slowly. Finally, budget for ongoing costs (food, water treatments, plants) not just the purchase price.

Tank Size Guide

Nano (5–10 gallons): Chili Rasbora, Dwarf Rasbora, Galaxy Rasbora
Medium (10–20 gallons): Harlequin Rasbora, Lambchop Rasbora, Clown Rasbora
Large (20+ gallons): Scissortail Rasbora, Red-tailed Rasbora
