I've been keeping a 12" cube with some live rock, various corals (soft, LPS and some SPS) and a single small fish for a while and really like the compact depth. It makes maintenance so much easier and allows me to keep the lighting reasonable.
All of my creatures seems happy so I'd am thinking...
Same thing happened to me. He was small, but stuck around the same spot. Then one day disappeared!
I had a small cup coral on the back of a rock, so it was hard to see him, but could see his ball tipped arms swinging. I fed him some shrimp one evening and then haven't seen him since. :worried2...
My urchin looks just like that from my TBS rock. It roams the rock eating coralline algae. I do see it try the walls and other surfaces on occasion, but when hungry, it will crew on my rock for sure.
I did find a new small one. I wonder if it had a baby... ;-)
Where did you buy in NEO that you had issues with?
I've been mostly buying from Tidal Gardens direct since I live in the area. That way I have a say on the quality of the piece of coral I buy from them. ;-) One I bought that was not part of their monthly online sale needed some TLC to remove...
Those are some nice tunicates and sponges on the LR. I've found my limpet snails eating some of the more interesting sponges, so keep an eye out for those guys.
Unfortunately my cool branching and ball sponges have slowly died off. I just have the orange lettuce one left and my tank doesn't...
I've seen them too, but have noticed that they have started to disappear as well.
I am seeing some interesting leafy green (seaweed?) and red macro algae growing, which adds some additional color and dimension to my TBS rock. :-D
It's like when the seasons change. I always wonder what else I...
After some more research :reading:, I found out they are the byssal threads produced by the scallop as it attempts to anchor itself somewhere. Silly little bugger likes to hop around the tank to find the best flow.
I hope I can get your help identifying these strange white tendrils growing on my glass and the back wall of my biocube.
Two of them have appeared to latch onto the foot of my flame scallop, so I am guessing they are not 'friendly'.
This worm looks nothing like the one I saw on Melev's Reef (http://www.melevsreef.com/node/361).
If I said it looked like something, see this site (http://chucksaddiction.thefishestate.net/hitchworms.html) and look at the fifth row of the nemertea. It looked a little like that.
Here is another...
