Tunicates? Sponges? I found this with pics. I also have some in my tank but I think they are yellow. They tend to be on the bottom of overhangs or rocks. http://www.thereeftank.com/forums/f6/clear-tubes-on-live-rock-185437.html#/topics/185437?page=3
That is exactly the same! They do seem to be annoying my star polyps. I wonder if I should invest in different hermit crabs?
Yeah, mine don't seem to be bothering anything but if you think it's bothering them you might try picking them off or try one of the crabs. I haven't noticed my crabs munching on mine but honestly, I haven't seen the blue one in a while so who knows!
So I found these 3 guys on my Hammers tonight. At first I thought they were the red ones I had before but after looking I'm not sure what kind they are. I also am not sure how I got them as I used the flat worm exit not too long ago. I guess I'll be using it again if I see another one.
That last picture almost looks like a polyclad flat worm which is an invert predator. Do all 3 look the same? I don't know what they are but all three being on the same coral is a bit worrisome to me.
Pretty much. The first one I pulled had a red spot in the center. I think you can see it in the pic. Should I just run flatworm exit again? Well ... I found 3 more on the same hammer along with what looks like some tissue loss so I decided to go ahead with the exit. In reading he instructions again I am pretty sure I didn't dose it right last time! It said 4 drops per 20 LITERS or 5 gallons and I am pretty sure I read it as 20 gallons ... no wonder I really didn't see any activity after I used it before. This time just a few minutes after I used it I could see them running all over the hammer! I sucked them out with a pipette as soon as I saw them so they hopefully wouldn't add to the toxicity. I pulled several off the hammer and 1 or 2 off of a Duncan in the middle and 2 off of the frog spawn on the other end of the tank. I looked at and squirted every coral just trying to find more but never saw anything else. I went ahead and cleaned the filter sock and added the carbon so hopefully it will take care of any I didn't see. I'll check on everything again here in a bit to make sure I don't see any more. Hopefully it took care of the problem this time!
Anybody know what this is? I seen it on a leather coral. I removed it, in case it was harmful. I didn't think I would see it again.
The reason I asked is it looks a little like this. https://www.lionfishlair.com/hitchhikers-guide/nudibranch-predatory-1/
It was mobile, that I could tell. It was in a high flow spot, but looked like it had control over moving. It moved on the leather coral while I was trying to find something to suck it out with. It looked like it had baby xenia polyps forming on its body. It looked similar to that one, but it was solid white.
That's a coral eating nudi. Good choice to remove it. Keep an eye out....where there's one there are often others!
That's what I was afraid of. Hopefully it doesn't cause too many problems. I will keep an eye out for more.
I was totally thinking nudi! Wasn’t sure which kind but I’ve seen tiny versions on my montis! If you have montis, check the under side and check at night. It’ll look sort of like sand gathered ...
