I want to add a couple of plants to my fahaka puffer's tank. Its a 120 with one doulbe four foot fixture and one double three foot fixture. Both fixtures have normal indoor bulbs I got from home depot. Is there any plant I can get for the tank that gets to be a decent size, is hardy, and can live in these conditions? I have some java ferns and anubias right now. I would like something taller and fuller. Also this should be a another post but I get real think sludge like algea on my anubias. Any clue what that might be?
