I have a 5 gallon tank as an "extra" I was putting the fry from my guppies in there, but now only have a pair of platties which gave birth the day after I got them. I'm looking for a single plant to put in here to combat the algae. It's not out of control. my other tank cleared up nicely after I added my last round of coop plants. More and more ramshorn snails are appearing daily, but I will be removing them manually. Just curious if anyone had experimented with single plants that can starve out the algae in the water. (I already reduced the light)
