Najas Guadalupensis | Guppy Grass

guppy grass

I was searching for a certain kind of aquarium plant. I needed something that could house my baby fishes. Something dense but enough spaces for the fries to hide and move. For some reason, it’s kinda hard to find it near my area. I decided to get rid of the java moss because, in my opinion, it is hard to maintain and it looks messy. Luckily, I found the one that I was looking for and purchased some at a local fish store.

It is called Najas Guadalupensis. It’s a fast growing aquatic plant. They also call it southern/common water nymph or guppy grass because they serve as suitable hiding spots for baby fishes, especially guppy fries. It can be floated or rooted.

The stem plant’s height can reach up to 35 inches (90 cm). It’s also known to remove toxin in aquarium water, pulling nitrate in the water column. The plant originated in North, Central, and South America and some parts of Canada. They are commonly found in fresh and brackish lakes, springs, canals, streams, and ponds.

Water nymph is an undemanding grass in a freshwater aquarium. You can just let it float and in a few weeks-time, it can overtake your tank.The stem produces many branches. It sends out thick roots that get ahold of the substrate. If you plant this in the background, it will create a wall of foliage.

Najas guadalupensis is a hardy plant and one of the easiest plants to grow as it does not require CO2. It is brittle. That is why, it is recommended to only introduce small types of fishes in your guppy grass aquarium. It also serves as food for some vegetarian cichlids.

Guppy grass is good for amateur aquascapers as it promotes oxygen rich water. Dwarf shrimps also love najas grass. They stay safe with a thick bunch of these easy to care for plants.

This is interesting. Does it flower? Yes. Tiny flowers occur in the leaf axis but they are very small and can barely notice them.

Other details:

  • Growth rate: Fast
  • Propagation: Clipping
  • pH requirement: 6.0 – 7.0
  • Temperature: 72 – 84 °F (22 – 28 °C)
  • Lighting condition: Low to high light (the more light the brighter green it will be)
