Diving through species care sheets & parameters…
An independent educational knowledge platform and digital field guide dedicated to empowering aquarists with scientific species profiles, water chemistry tools, and biotope planning resources.
Freshwater & saltwater verified profiles
Low-tech & high-light aquatic flora
Bioload, water parameters, volume & compatibility
Science-backed animal welfare first
Aquarium keeping is one of the most rewarding branches of applied biology. However, beginner and experienced fishkeepers are routinely misled by commercial marketing claims, uncycled miniature tanks, and incompatible stocking combinations sold without warnings.
Roshan Aquva World was created to replace guesswork with verified science. We provide comprehensive, accessible data on water chemistry tolerances, behavioral temperaments, vertical swimming zones, and sustainable habitat design.
Whether you are setting up your very first 10-gallon planted community tank or managing a high-tech Amazonian Discus biotope, our mission is to ensure every aquatic organism in your care thrives in healthy, stable conditions.
Every species profile, chemistry tool, and care guide adheres to rigorous criteria designed around long-term biological stability.
Care parameters, thermal boundaries, and minimum aquarium volume requirements derived from wild biological biotope data and established veterinary guidelines—never scaled down for commercial sales convenience.
We advocate strictly for complete biological nitrogen cycle establishment, generous horizontal swimming footprints, and zero stress-inducing territorial cohabitation.
Demystifying complex water chemistry, pH carbonate buffering (KH/GH), and microbial filtration mechanics into actionable, clear step-by-step guidance for beginners and advanced keepers alike.
Our compatibility algorithms and hardware recommendations are 100% independent. We do not promote inadequate micro-tanks or uncycled starter kits that compromise aquatic life.
Our 4-stage publication protocol ensures that care requirements are accurate, safe, and up to date.
Every species profile begins with wild native habitat analysis: Amazonian blackwater, African rift lake alkaline basins, Southeast Asian peat swamps, or Indo-Pacific coral reefs.
We synthesize temperature tolerances, pH ranges, dGH water hardness, adult growth sizes, and dietary requirements from vetted ichthyological registries.
Temperaments are mapped across vertical swimming layers (Surface, Mid-Water, Substrate) to identify territorial boundaries, fin-nipping hazards, and schooling requirements.
Our editorial board continually refines recommendations based on evolving aquatic science, biological filtration advancements, and verified hobbyist feedback.
Information on Roshan Aquva World is provided for general educational purposes. Aquarium requirements can vary depending on individual animals, aquarium conditions, source information, and husbandry practices. Content is periodically reviewed and may be updated as information develops.
Our editorial team welcomes keeper corrections, scientific inquiries, and species contribution submissions.
