So came to my tank last night, it was under dusk setting (2 T5 bulbs only), and I saw 2 of my rock flowers looking weird, or different from their normal. So upon closer examination it looks like they were spawning, I couldn't believe it. This went on for about 30 minutes that I saw, but just amazed me. That's the kind of events that keep me so hooked on this hobby. The two that were spawning were alternating in their release. Hard to see the milky substance in the image, but I can't get the video uploader to work. The little milky stuff is on the bottom lip of the orange one in the middle. Good stuff!
