My cichlids didn't love to eat, but still ate (ruined) ferns and anubias I put in their tank. For those who say that cichlids won't eat those plants, they are wrong. Maybe small cichlids have less of an interest.
However, are you interested in any Windelov java fern? I have a lot of that that I'm considering selling off.
May I ask why you think ferns and anubias are going to be algae control?
