Can Pennywort (Hydrocotyle vulgaris) be grown in a fish tank? With suitable light and the right method, yes.

Pennywort is an amphibious plant that can be grown both on land and in water. It can be cultivated in soil or in water, and its leaves and rhizomes can be completely submerged in water. So some gardening enthusiasts have a question: can Pennywort be put in a fish tank? The answer is yes. Below, the editor will tell you the method for growing Pennywort in a fish tank.

Can Pennywort be put in a fish tank?

Pennywort is easy to grow and takes shape quickly. Even when its leaves are in water, it can still grow normally, so Pennywort can absolutely be placed in a fish tank and can create a very good ornamental effect.

How to grow Pennywort in a fish tank

1. Selection of plants

Generally speaking, the plants grown in a fish tank should mainly be vigorously growing Pennywort, because its growth rate in water is relatively slow. If a plant that is itself rather weak is used in a fish tank, it can easily die.

2. Fixing the roots

In order to keep Pennywort fixed in the fish tank so it does not float to the surface, its roots need to be fixed to the bottom of the tank. The method is to gently press down the roots with small stones, so that its leaves will be completely submerged in water. This point differs from the hydroponic method for Pennywort.

3. Supplemental lighting

Pennywort needs light to grow. When placed in a fish tank, the refraction of water may cause insufficient light, so lighting is needed as a supplement. If the fish tank is placed in a relatively bright location where it can receive scattered light, that is ideal.

4. Replacing the plants regularly

Because respiration of Pennywort is hindered in a fish tank, its growth is extremely slow and may even stop. So after 1-2 months of underwater cultivation, it should be taken out of the water and replaced with other plants, to avoid the plant dying from being kept too long.

Can Pennywort be placed in a fish tank?

Actually, it is not impossible to put Pennywort into a fish tank. Many gardening enthusiasts have tried it, and Pennywort placed in a fish tank can still grow. It is just that the growth will be slightly worse, and it feels inferior to Pennywort grown by other methods.

When Pennywort is placed in a fish tank, in most cases it is simply put directly into the water, with the entire plant submerged.

There are basically two approaches. One is to put Pennywort into the fish tank when it is growing poorly and weakly, because Pennywort grows very fast, so it still takes shape quickly. The other is to first grow Pennywort to a relatively good condition, and then put it into the water.

After putting Pennywort into the water, small stones or similar items need to be placed on top to keep it from floating up.

What to pay attention to when growing Pennywort in a fish tank

First, although Pennywort in a fish tank can grow, its growth is actually inferior to that of Pennywort grown in soil, in water, or in a half-soil half-water setup. Growth will be relatively slow and may even stall. Second, note that when growing Pennywort in water, you must prevent it from floating up; it is best to press it down with small stones or similar items, which also has a decorative effect. One more point: if growing Pennywort in water, it is best to replace the plants regularly. Usually once every 1/2 months.

Because Pennywort is suited to half-soil half-water cultivation, quite a few gardening enthusiasts want to know: can Pennywort be put in a fish tank? Through the practice of gardening enthusiasts, it has been confirmed that Pennywort can be grown in a fish tank, only its growth state is not as good as with half-soil half-water. Let us look at the feedback below.

In a fish tank, Pennywort is in the vast majority of cases simply placed in the water, that is, completely submerged. Through the practice of gardening enthusiasts, it has been found that Pennywort can survive in a fish tank, but grows very slowly and may even stall. In short, its growth state is poor, but this does not prevent Pennywort from being grown in a fish tank as an ornamental grass.

First, let us look at a photo of the results from a gardening enthusiast:

This gardening enthusiast's approach is: when the Pennywort is in poor condition, taking advantage of Pennywort's fast growth, cultivate several extra pots outside. I put it into the water only after it has grown well, and press small stones on the pot, otherwise it will float up. The point is that underwater Pennywort almost does not grow, so replace the pot every 1 or 2 months.

After all, Pennywort is not an aquatic plant, so it is hard for it to grow as fast in water as in air. Gardening enthusiasts need to understand this point.
