Where do they go when they disappear? Every single shroom I've ever had (aside from a double ric that never moved) runs away. I don't know where they go. Why would they leave? I have a 55 gal w/ 2 x 96Watt PCs & 2 x 96Watt Actinics. Surely this would be enough light. And I feed them DTs Phyto. Where do I go wrong?
