The Best Aquatic Plants for a Red-Eared Slider Tank

Red-eared slider turtles are popular pets known for their vibrant red stripes on the sides of their heads. In the wild, these semi-aquatic turtles live in ponds, lakes, rivers, and wetlands surrounded by aquatic vegetation. Recreating their natural habitat in captivity with aquatic plants can provide many benefits. Plants help filter the water, provide security, serve as food, and create an aesthetic environment. However, not all plants are suitable for a red-eared slider habitat.

When choosing aquarium plants, it’s essential to select species that are turtle-safe. Some common aquatic plants are actually toxic if ingested. You’ll also want to opt for hardy plants that can withstand some munching. Red-eared sliders are likely to snack on any vegetation within reach.

Here are some of the best aquatic plant options to consider for a red-eared slider tank

Anacharis

Anacharis is a popular choice for turtle tanks. This freshwater plant has long, bright green stems with small leaves. It grows quickly and helps absorb nitrates and ammonia. The rapid growth also makes it ideal for hungry turtles. Anacharis oxygenates the water and provides ample hiding spots. It can thrive in both low and high light. However, the plant does not attach to anything and will need to be anchored.

Amazon Sword

The Amazon sword plant has stiff, broad leaves that provide shade and security. This rooted plant propagates easily by sending out runners. It grows up to 20 inches tall and removes nitrates from the water. Amazon swords are durable yet soft enough that snapping turtles won’t chip their beaks if they bite the leaves. The slight texture also helps clean turtles’ shells when brushed up against.

Anubias

Anubias features broad, thick leaves on a short stem. It grows slowly and requires only low to moderate light levels. The tough leaves hold up well to turtle nibbles. Anubias helps filter waste materials and resists algae growth. Its short stature and broad leaves are perfect for resting spots. Use aquarium glue or fishing line to anchor it to rocks driftwood or the bottom of the tank.

Duckweed

Duckweed is a miniature floating plant with tiny leaves. It multiples rapidly, helping soak up excess nutrients that contribute to algae growth. Duckweed also provides shade for a turtle habitat. Both red-eared sliders and yellow-bellied sliders nibble on these free-floating plants. Be sure to scoop out excess duckweed regularly before it completely covers the water’s surface.

Java Fern

Known for its hardiness, java fern thrives in turtle tanks. This low-light plant has thick, forked leaves that provide hiding places. Java fern helps reduce ammonia and nitrate levels in the water. It grows slowly and requires little maintenance. Java fern can be anchored to rocks, wood, or the aquarium floor to prevent uprooting by curious turtles. The leather-like leaves stand up well to nibbling.

Hornwort

With its feathery, bright green leaves, hornwort gives a pleasing aesthetic to turtle tanks. It grows quickly while helping control algae due to its rapid nutrient uptake. The stems provide thick cover. Hornwort does not require planting and can float freely. Turtles tend not to feed on it often due to its stiff texture. But rest assured it is safe if consumed. Routine trimming maintains its appearance and prevents overtaking the tank.

Water Lettuce

The attractive, floating water lettuce has round leaves with slightly ruffled edges. It provides shade while inhibiting algae growth. Water lettuce effectively removes dissolved organic compounds. As a tasty treat and supplemental food source, red-eared sliders enjoy munching these floating plants. Monitor growth closely and remove excess plants to maintain open swimming room.

Water Hyacinth

With bulbous, glossy leaves and lavender flower spikes, water hyacinth adds beauty to a habitat. The plant’s extensive root system absorbs ammonia, nitrates, and phosphates efficiently. Water hyacinth reproduces rapidly, so you’ll need to regularly thin it out. It also provides tasty greens that supplement a turtle diet. The edible leaves and stalks have a high moisture content.

Java Moss

Java moss is a versatile freshwater plant composed of dense, stringy filaments. It thrives in low to moderate lighting. The moss attaches to rocks, driftwood, and tank decorations. Java moss efficiently absorbs dissolved wastes while inhibiting algae growth. Its flocculent structure provides endless nooks for small turtle species to explore. And its secure attachment prevents it from being uprooted.

When choosing plants, opt for soft-leaved varieties, as they are the safest for red-eared sliders if ingested. Avoid sharp-edged and spiky plants. Introduce plants gradually to monitor your turtle’s interest. Anchor plants well or use protective barriers to prevent uprooting. With the proper selection, aquatic plants can create a thriving ecosystem in your red-eared slider habitat.
