Every cluster on Fishkeeping.io lives here. Each topic below links its published guides; new guides are added on a regular schedule, so these lists grow every week.
Getting started
The first month, in the right order: choosing and setting up the tank, cycling it before any fish, and stocking it honestly. Start with the tank setup guide, then the fishless cycling guide, then the 10-gallon stocking guide.
Water quality
The invisible half of the hobby. The water parameters guide decodes pH, KH, and GH; the water change guide sets the maintenance rhythm; the ammonia guide and nitrate guide handle the two numbers that matter most; new tank syndrome and cloudy water cover the classic first-month emergencies.
Fish care
Species-by-species care that respects how fish actually live. Currently: the betta care guide and its troubleshooting companion, why a betta stops eating. Guppy, tetra, corydoras, and more species sheets are on the publishing calendar.
Plants and aquascaping
Live plants are the cheapest water-quality equipment in the hobby. The low-maintenance plants guide is the hub: which species forgive a beginner, and why. Planting technique, fertilizer, floating plants, CO2, and plant-troubleshooting guides publish through early October.
Algae and problems
Algae is a message before it is a nuisance. The algae identification guide reads the message and fixes the cause without dosing anything. Dedicated guides to brown algae, green water, black beard algae, hair algae, blue-green “algae,” and algae-eating crews publish through September.
Equipment
Gear, sized honestly. The filter guide explains sponge versus hang-on-back versus canister and the turnover rule that sizes them. Heater and test kit guides are scheduled next on the calendar.
