You may want to do a search on flatworms to make sure that those are not you little slugs, if they are you can get rid of them before they get too established.
Lets see a full tank shot.
Your tank looks great, I just love the aquascaping.
If you find one of the 'slugs' on the glass, grab a magnifying glass then shoot your picture through it. Could also be the stamella snails (I need to find the correct spelling and tape it to monitor )
Easiest way to get rid of flatworms if that's what you have is to use salifert flatworm exit. However I'd make sure that's what you've got first. It could just be juvenile stomatellas.
Again, you all are the best. Another thing I've noticed lately, is millions of teeny tiny star shaped critters all ove the glass. Hundreds of them look just like mini-transparent star fish. I can't wait to hear what they may be..........Hmmmm
I'm bettin' you are right. I didn'nt realize there were so many kinds of hydroids. Other folks out there described just as I see on my glass. At this time I have no fish and only a handfull of soft coral. It still is in need of settling in for everyone to be really happy in there. So far, so good. Hope to have some improved pics to share this coming weekend. :cool1:
