If you're using a heated storage tank, you'll require a different means of heating your water, such as using an additional heater or lamps to heat up the room where your tank is kept.

Lighting Is Super Important!
Do not underestimate the value of lighting your aquarium! In a small aquarium, proper lighting is crucial for plants to grow and stay healthy.

A Good Filtration System Can Be A Lifesaver
The importance of a suitable filter cannot be overstated when it comes to small aquariums.

For a small tank, a great screen should be slow but have a flow rate between 4 and 5 times the size of the entire tank. This will allow your fish to get good filtration and let them get rid of waste products more often for easy maintenance.
Don’t Forget Green Aquarium Plants!
There’s no need to strictly use green plants for an aquarium to thrive, but they can help. Photosynthetic plants provide your fish with a source of nourishment while helping to oxygenate the tank and keep water quality high. If your tiny tank looks a bit drab, additional plants may be the perfect touch it needs.Generally speaking, the healthy growth of plants in an aquarium means that the water is healthy and suitable for the fish. If you find it challenging to get your plants to grow, adding a small amount of fertilizer to the water may be beneficial. This might help motivate them and provide a boost to their growth.
Despite all you attempt, plants inevitably end up dying. In these scenarios, removing any dead or decaying plants from your storage tank as soon as possible is essential. Decaying plant matter can harm your fish and result in water quality issues, and these adverse effects are amplified in a tiny tank. If one of your plants looks unwell, don t be afraid to say goodbye.
