Sally Russell –
I’ve had Frogbit in my 20-gallon tank for three months. It grows quickly and stays floating naturally. My betta fish loves to hide under it, and the water looks cleaner since I added it. Easy to maintain and no issues so far.
Oliver Wilson –
The plant arrived healthy and spread well within a week. It helps reduce algae growth and gives a natural look. I didn’t have to adjust lighting much, which is great for a beginner setup.
