Walking through aquarium shops, you’ll notice lush plants mixed with true underwater species. This beginner guide explains why non-aquatic plants end up there, how to spot them, and what to do if you already bought one. Learn true aquatic options, conversion tips, and smarter shopping to avoid disappointment and failure.

Getting the light right is the key to thriving aquarium plants. Start by matching plants to PAR levels, then set a stable photoperiod with a timer. Balance spectrum, Kelvin, and CO2 with nutrients. Keep changes gradual, watch algae, and use practical setups anyone can copy to succeed in your tank.

Choosing real or plastic aquarium plants comes down to maintenance, budget, and goals. Live plants naturally filter water, oxygenate, and enrich fish behavior, but demand light, fertilizers, and care. Plastic plants require little upkeep yet offer no filtration. Many aquarists blend silk realism with live growth for balance in tanks.

Stalled aquarium plants usually signal an imbalance in light, CO2, or nutrients. This beginner guide helps you diagnose issues, adjust gradually, and build a simple routine to keep plants thriving. Learn to read signs, test basics, and optimize light, carbon, and nourishment—plus flow, substrate, and compatible plant choices for growth.

Setting up a planted aquarium is exciting, and CO2 is optional for many beginners. This guide explains when CO2 helps, how light and nutrients interact, and how to choose a low-tech, CO2-assisted, or DIY approach. Learn balance, avoid algae, and tailor a setup to your tank, budget, and goals today.

Ask how many fish per species? The answer is simple: small shoalers thrive in groups.

Sixty litres offers a beginner-friendly balance: generous space for a peaceful community, yet compact enough for homes. Stocking depends on size, shape, and care. With good filtration, weekly water changes, and live plants, a sixty-litre tank can house about 8–20 small fish, plus bottom dwellers, readied gradually through patient planning.

Goldfish and most tropical fish generally should not share a tank. Temperature, diet, and behavior differ, creating stress and disease risks. Some temperate species can coexist in filtered setups, but it’s the exception. This guide explains why mixing is tricky, safer tankmates, and how to create compatible communities if attempted.

Tankbusters look cute as juveniles but can outgrow home aquariums, producing heavy waste and aggressive behavior. Buying them without checking adult size risks stress, escapes, and heartbreak. Research species, plan for adult tank length and filtration, and choose smaller alternatives. If you already own one, upgrade or rehome responsibly today.
