Tissue culture plants are cultivated in sterile lab settings ensuring your plant is free from pests, snails and algae! These are young specimen that are grown in emersed forms. Gel should always be removed prior to planting.

Azolla Caroliniana (Mosquito Fern)

Azolla is a small, fast-growing floating aquatic plant that forms dense surface coverage in planted tanks and pond setups. Also known as Mosquito or Water Fern, it’s a popular choice amongst aquarium hobbyists and pond enthusiasts.

Its tiny overlapping leaves resemble miniature water ferns, making it a great option for anyone in search of a unique, low-tech floater. Azolla is primarily green, but can produce a reddish-purple hue when kept under high lighting. It is a very fast-growing plant that will require periodic harvesting to prevent light blockage. Floating plants offer several benefits such as algae control, improved water quality and a sense of security for tropical fish.

Floating Aquatic Plant Care & Information

Caring for floating aquarium plants—like Azolla, Salvinia, Frogbit, Red Root Floaters, Water Lettuce or Duckweed—comes down to balancing light, nutrients, water movement, and routine maintenance. Here are some tips to help you get started!

How much light do floating plants need?

Most floating plants do best with high light. In most setups, moderate to high lighting from quality LED fixtures works best. Aim for an average of 8–10 hours of light per day. Be mindful—too much lighting can cause algae blooms and increase competition for nutrients.

Do floaters need fertilizers?

Floating aquatic plants offer a great source of natural filtration and help absorb nutrients. Supplementing with a liquid fertilizer that contains nitrogen, phosphorous, potassium, and micronutrients like iron and magnesium can support healthy growth in nutrient-deficient tanks. If you’re unsure, signs of nutrient deficiency include stunted growth and yellowing leaves.

Maintenance and water flow

Floating plants are fast-growing and will require regular thinning to ensure submerged plants receive light. Remove dead or decaying leaves to maintain water quality. Provide your floaters with gentle flow—strong surface agitation can cause damage. If needed, consider adjusting your filter’s output or use a baffle to diffuse the circulation.
