Here is my first two plants, java fern and anubia. I have not yet got to buy the seachem flourish comprehensive and excel because they did not have it at petco. How long can these plants last without ferts? And I think my LEDs on this fluval View are strong enough to keep them growing. I hope. I tied the fern to my driftwood to keep the roots actually out of the gravel. How do they look? (I'm currently dealing with cloudy water though)
