Fern Java (Microsorum pteropus) in Terracotta Pot
This plant is very hardy and grows well in a wide range of water parameters. Fish tend not to nibble at these as not only are the leaves very tough but apparently they taste disgusting. This is one reason why they are a popular plant in aquariums that contain herbivorous fish.

I added this fern to my community tank with guppies and it has grown well without any fish eating the leaves. The terracotta pot looks natural and adds a nice touch to the setup. Easy to maintain and stays healthy even in fluctuating water conditions.

The plant has been growing steadily in my 55-gallon tank. I didn’t expect it to be so resilient. My fish haven’t touched it, which is a relief. The pot is sturdy and fits well in the background.

Great choice for beginners. It’s hardy and doesn’t require much attention. I’ve kept it for over six months and it’s still thriving. The leaves are lush and green, and it blends well with other plants.
