Benefits of Emersed Aquatic Plants (Pros and Cons):
Many submerged aquatic plants can
also grow emersed. It is very important to add live plants to your aquarium
because they have many benefits. They look attractive but many new fish keepers
think that they need high maintenance & will probably not grow in harsh
conditions. There are many live aquatic plants that are adapted to grow in
aquariums in harsh conditions & they don’t need high maintenance. In this
article, I have added pros and cons of emersed aquatic plants & aquarists
usually prefer such plants for their ponds because they bury their roots in
substrate or at the bottom of water, & grow most of the vegetation outside
water.
Pros of emersed aquatic plants:
Emersed aquatic plants look very
beautiful in aquariums. They grow inside water & their upper parts grow out
of the water surface. Have a look at benefits of emersed aquarium plants:
Help fish:
Fish use plants for hiding &
sleeping. They eat live plants. Tall plants can lower light intensity. Fish
feel safe & plants can calm them which can lower the illnesses that are
caused due to high stress. Fish show vivid coloration in the presence of plants
& if they are not stressed, they will spend more time in the open.
Attractive:
If you introduce live aquatic
plants to fish tanks then they will provide a natural appearance. Use fake
plants to give a natural look to your fish tank, but still, they are matchless
to the beautiful colors that live plants show, & bushy plants look more
attractive than tall plants. Emersed plants have their upper part outside water
& they may grow flowers & leaves at the surface of water. Many
aquarists remove canopy & allow plants to grow outside. Your room will look
more attractive with plants growing outside tanks.
Natural filters:
When the nitrogen cycle completes
then the only remaining toxic chemicals are nitrates. However, they are less
toxic than nitrites & ammonia. The only way to wipe out nitrates from
aquariums is by using frequent partial water changes & by using live
plants. Nitrates fertilizes the plants, & plants filter your aquarium water
& keep aquarium inhabitants healthy. Emersed plants have their top part
growing outside water but they absorb toxic chemicals from water.
Encourage breeding:
Many fish use plants for
depositing their eggs & they will not breed quickly if your tank does not
contain live plants. If you want to setup a breeding aquarium then it is very
important to introduce live plants. It can reduce the stress levels of your fish
& allow them to hide their eggs inside plants.
Sell the cuttings:
Stem plants can propagate when
you trim its stem. It helps in reducing the height of plants & allow lower
leaves to have access to aquarium lights which is required for photosynthesis.
Hence if you think that your plant is growing out of control & they are
spreading abruptly then trim it & sell the cuttings. Many aquarists sell
them online & fish stores can give you a little money or discount when you
offer them your new plants.
Reduce algae growth:
Plants balance the ecosystem of aquariums & avoid unwanted algae from appearing by consuming nutrition that are responsible for the growth of algae.
Stabilize PH:
Live plants can generate oxygen
during the day, which is consumed by inhabitants & assists in stabilizing
the water PH. Fish exhale carbon dioxide, which is consumed by plants. CO2 acts
as a food for the live plants.
Improve health of substrate:
Plant roots can help in improving
the health of the substrate & keep your tank healthy.
The lack of oxygen in the lower
layers of gravels can allow anaerobic bacteria to grow in these regions which
is dangerous for the inhabitants. Keeping bigger layers of gravels can increase
the chances of anaerobic bacteria which release hydrogen sulfide gas in bubbles
from the depth of gravels. Roots of live plants break anaerobic pockets in the
gravels that fix this issue.
Keep gravels in its location:
When aquarists build structures
in aquariums, then plant roots will assist in keeping the gravels or substrate
in its location. This will keep the structure strong & overtime it will not
flatten out.
Decrease water temperature:
If you are using a tank light
then it will heat water & plants will help in decreasing water temperature.
Shelter:
Certain emersed plants will
provide shade. Hence that place of aquarium will have lower light & will
allow fish to hide. Fish that like to live in the darkness can use this shade
as a shelter.
Colonies of good bacteria:
Large surfaces of aquatic plants
can promote good bacteria which is required for nitrogen cycle.

Survival of fries:
Babies can use plants for hiding
from adult fish. Adult fish consider little fries as food & eat then. Fries
feed on plants.
Cons of emersed aquatic plants:
Everything has its pros and cons,
& plants are not exceptional. Have a look at disadvantages of keeping
emersed aquarium plants:
Decompose:
When aquatic plants die in
aquariums then they decompose which pollutes water. It can be toxic to
inhabitants that can’t tolerate chemical change.
Problematic fish:
Fish like Goldfish & Cichlids
will eat your complete plant. Goldfish will uproot them.
Reduce filter efficiency:
Plants can hold waste particles
& remaining food in its roots which can lower the efficiency of filtration.
Trimming:
Trim plants regularly to stop
them from growing abruptly.
No canopy:
Emersed plants have their upper
part outside water & many aquarists remove the tank canopy to allow the
plant to grow taller.
Prevent photosynthesis:
Emersed plants grow their vegetation mostly outside water. The top part of emersed plants can prevent light from reaching the lower leaves. Hence it will prevent lower leaves from photosynthesis.
