Why BMI Is a Crock, in Pictures. So, the Guess The Rotund's Height and Weight game gave me an idea. (Oh, and hey, if you want to see a scatter graph of the results, there's one here now.) I talk a lot about how BMI is bullshit, but we all know talk is cheap.
As suggested in the above links (Thanks! ShellaB, for posting those links -- The first one was especially useful.), you can use monofilament plastic fish line to tie the fern to the basket, if needed. I stuffed my staghorn's basket with a combination of leaf litter, spaghnum, and Spanish Moss.
It spreads quickly and has the same growing requirements as Java fern. Java moss can be attached to wood, rock or left free floating in the aquarium. This plant is readily utilized by spawning fish and is a good hiding place for tiny fry. It is one of the most widely used plants for this purpose.
