I have one green 'watermelon' mushroom. Since I've got it (2-3 months ago), the thing has yet to open up fully and look good. I feel like I have moved this guy all over my tank to no avail. See video below (30 seconds into video) for his current location: 10-10-2012 Aquarium Update - YouTube So has LR come to a consensus on mushroom placement? I was thinking medium light/low flow.. but I've even tried that. What are the chances he is sick or just a 'dud' lol.
