FISH TANK ARTICLES

Healthy plants transform an aquarium—soaking up nutrients, stabilizing water quality, and making fish feel at home. Light and nutrients are essential, but carbon dioxide (CO2) is the engine that turns them into growth. If you’ve tried stronger lights and fertilizers yet still battle algae or weak plants, a CO2 plan may be the missing piece. This guide covers why CO2 matters, the options (DIY and pressurized), how to dose safely, and how to keep your fish comfortable while your plants thrive.
Do You Need CO2? Understanding Plant Demand
Not all planted tanks require added CO2. Many popular species (Java fern, Anubias, Cryptocoryne, Amazon sword) do well in “low-tech” setups with moderate light and liquid carbon sources. You likely need CO2 if:
- Light is medium to high and plants pearl briefly or not at all.
- Fast growers stall or melt despite good fertilization.
- Algae increases after raising light but growth doesn’t.
Before adding CO2, confirm your lighting is appropriate and stable—unbalanced light drives algae. For context on light intensity and photoperiods, see our lighting guide.
CO2 Systems: DIY vs Pressurized
Both deliver carbon, but differ in cost, control, and consistency.
- DIY (yeast/sugar or citric acid/baking soda): Inexpensive and good for small tanks (5–20 gallons). Output fluctuates as mixtures age; frequent resets needed.
- Pressurized (compressed cylinder + regulator + diffuser): Most stable and controllable. Higher upfront cost, but precise bubble rate and easier long-term...

Regular water changes are the single most powerful habit in fishkeeping. Done right, they remove dissolved waste, stabilize pH and hardness, prevent algae, and keep fish stress low. Done wrong—or skipped entirely—they lead to cloudy water, ammonia spikes, and sick fish. In this guide, you’ll learn exactly how often to change water, how much to change for different tanks, the tools to use, and practical tips to avoid common beginner mistakes.
How Often Should You Change Aquarium Water?
There’s no one-size-fits-all answer, but you can dial in a schedule by considering your tank’s bioload (how much waste your fish and feeding produce), filtration, and plant growth.
- Typical community tanks (10–40 gallons): 25–35% weekly.
- Heavily stocked tanks (livebearers, goldfish): 35–50% weekly.
- Lightly stocked or planted tanks: 15–25% weekly; many planted “low-tech” tanks thrive at 25% every 1–2 weeks.
- New tanks (< 8 weeks): 25–30% every 3–4 days if ammonia or nitrite are detectable.
Real-world example: A 20-gallon guppy tank with growing fry and hearty feeding will overwhelm a small hang-on-back filter. A 35–40% weekly change plus gravel vacuuming keeps nitrate in check and water crystal clear.
How Much Should You Change Each Time?
Smaller, more frequent water changes are safer and easier for beginners. Aim for a volume that keeps nitrate below 20–40 ppm and avoids big parameter swings.
- 25–35% is the sweet spot for most community tanks.
- 50%+ is appropriate for emergency ammonia/nitrite control, large rescapes, or after...

What Makes a Fish “Beginner-Friendly”?
Not all popular fish are “easy.” Beginner-friendly species share a few traits that make them forgiving as you learn the ropes:
- Hardiness: Tolerate minor fluctuations while you master water testing and maintenance.
- Peaceful temperament: Play nicely with a range of community tank mates.
- Modest bioload: Don’t overload your filter or demand huge tanks.
- Simple diet: Readily accept quality flakes, pellets, and occasional frozen foods.
- Clear care parameters: Temperature, pH, and tank size are easy to meet in common setups.
If you’ve never heard of cycling, start here: Understanding the nitrogen cycle. A properly cycled tank is the foundation that makes these fish truly “easy.”
Top 10 Beginner-Friendly Freshwater Fish
These species are widely available, hardy, peaceful, and colorful—perfect for a first community. Always confirm the final adult size and group needs before you buy.
- Zebra Danio (Danio rerio) — Hyper-active schooling fish that thrive in groups of 6+. Great at room-friendly tropical temps and very forgiving.
- Platy (Xiphophorus maculatus) — Hardy livebearers available in many colors. Keep 1 male to 2–3 females to reduce pestering; expect babies!
- Corydoras Catfish (Corydoras spp.) — Peaceful bottom-dwellers that love sand and soft flow. Keep in groups (6+) for confident, comical behavior.
- Guppy (Poecilia reticulata) — Colorful, active livebearers; easy to feed and breed. Keep more females than males for harmony.
- Swordtail (Xiphophorus hellerii) — Slightly larger than platies; do well in 20+ gallons. Gentle, bold swimmers for the upper/mid water.
- Harlequin Rasbora (Trigonostigma heteromorpha) — Tight schooling fish with striking copper triangles; best in groups of 8–10.
- Cherry Barb (Puntius titteya) —...
