I put a moss ball in my 5-gallon betta tank when I started up a few months ago. Other plants are java fern and anubias.

I noticed a few days ago that the moss ball had turned an unappealing olive-drab color (think of an army tent that's been in the sun for a year). I tossed it, since it sort of clutters up an already-small tank anyway.

But I'm curious if anyone has any info on what happened. The ball had grown some since I bought it, and even looked a bit shaggy. Color has always been good up to now.
