Aquatic plants VS ornamental fish

If you’re thinking about planting an aquarium, you may be wondering:  which fish will eat and harm aquatic plants? which aquatic plants are safe and good with fish?

Fortunately, there are some easy-to-grow varieties that aren’t harmful to fish. Hygrophila is one of these plants and is fairly common in many home aquariums. The leaves soften as the plant grows, and fish can eat it, too. Water sprite is another plant that isn’t harmful to fish. Its foliage is tough enough to resist most types of nibblers, but it isn’t a suitable choice for planted aquariums.

Silver Dollar fish are a common species of freshwater fish that eat plants and are a great choice for beginners. It’s not advisable for them to live with plants. Because they are found in brackish water, they are likely to eat live plants in your aquarium. As a rule, monos don’t do well with fast-growing aquatic plants. These fish are likely to be more successful if you have a variety of live plant species in your tank, and are especially good for aquaponic systems.

Monos are similar to Silver Dollar Fish, but they are a bit larger and tend to feed on vegetable matter. This makes them prime candidates for your home aquarium, where live plants aren’t available. Because they live in brackish water, they are likely to devour live plant material, too. Many types of aquatic plants don’t do well in brackish water, so they’re unlikely to eat your aquarium’s plants.

Other common plants that fish can’t damage include Potamogeton and Elodea. These are difficult for fish to digest so can’t be eaten quickly. Lemna, meanwhile, has an unpleasant taste that makes it unsuitable for fish to eat.

Aquatic plants like the java fern and water sprite are common choices for aquariums. However, these are not suitable for many types of fish, including the Silver Dollar fish, Buenos Aires tetras, Severums, Mono’s, and Cichlids. The main reason is that these plants are slow-growing and contain tough leaves, which are unpalatable to fish.

Most fish do not eat java fern, so you do not need to avoid it. In converse, hygrophila and rotala are commonly eaten by fish. Try a few plants and see which ones your fish don’t like. It may take a little experimentation to figure out which plants are best for your specific type of fish.
