I have three tanks of Gourami and I put duck weed in there for breeding. It disappears with in a few days. Are the Gouramies eating it or is it dying?
I had some in a betta tank (undergravel filter) and it disappeared to. The bettas would only try eating it once LOL, then left it alone. I was hoping to grow some for the pond, guess not. (Watersprite also dies off faster than it grows, don't know why..)DW is so prolific that most people curse having it. Usually very hard to get rid of and since yours disappears, the likely culprits are your fish.
