5 Best Aquarium Plants for High Tech Planted Tanks with CO2 Have you ever heard the words “low tech” and “high tech” being used when referring to a planted aquarium and wondered what the difference was? To put it simply, the more energy that goes into an aquarium setup, the “higher tech” it is.

Because a lot of energy is going into the system, high tech setups are often very costly and need more maintenance than a...

How to Save Your Baby Fish with a Breeder Box Most fish do not show any parental care toward their offspring, so when they lay eggs or give birth in an aquarium, the next generation can easily become a quick snack for the adults.

In an aquarium, we can help increase their survival rate even more by using a breeder box to contain the fry and protect them from larger fish. ...

How to Culture Microworms for Fish Fry Live foods are extremely useful when breeding fish because their enticing movements encourage the babies to eat and grow at a faster rate. However, some fish (such as betta fish, ram cichlids, and rainbowfish) produce miniscule offspring that are too small to eat traditional fry foods like live baby brine shrimp or crushed flakes. Instead, you can easily start a culture of micro, banana, or walter worms to keep the babies happy and healthy. What Are Microworms? A “micro worm” is a common name...

How to Use Root Tabs to Fertilize Aquarium Plants Is your live aquatic plant not growing or losing leaves, even though you’re giving it plenty of light and liquid fertilizer? Most aquarium plants can absorb nutrients from both the water and the substrate (e.g., gravel, sand, or aquatic soil), but some species prefer one method over the other. If your plant is a “root feeder” that favors consuming from its roots, then we need to give it a nutrient-rich substrate or ground-based fertilizers called root tabs. What Are Root Tabs?

Why is My Cryptocoryne Plant Melting? You just planted your new cryptocoryne (or crypt) plant in the aquarium, and it looks perfect for the first few days.
