I recently took a trip to the San Diego/Carlsbad, CA area to visit family and had the opportunity to explore local marine life. The eastern Pacific along the California coast is pretty cold (50-60F if memory serves) so I was curious as to what kind of critters I'd find. I managed to convince my...

In the Rochester area... Does anyone know if any LFS sell velvet sea slugs? Trying to avoid paying $$$$ for next day air shipping. Sent from my iPhone using Tapatalk

I bought a big blue pom pom Xenia rock a few weeks ago. I moved the rock a couple days ago. I noticed it was not looking as good as when I put it in the tank. Tonight I was cleaning the tank, doing water change, and found this on the glass. I believe it is a Phyllodesmium rudmani. It looks just...

have a small issue with hydroids. They seem to be decreasing in numbers over the past two weeks. Having never had them before I read up and found that the kind I have are common. Just kind of ugly on the glass. I found this pic online of the kind it looks like I have. There pretty small I am...

Its about 3" long.......

Its white, feels like rubber and is attached to the liverock. I just noticed it after I put the coral from the swap (which was great) to float.

What kind of crab is this and do i need to worry about anything in the tank with it? Also is it known for them to have feather dusters grow in the cracks and holes in its shell? You can kinda see what im talking about right above the shell in this pic Also what kind cucumber do i have?

I found a black nudibranch in my sump> Are these things reef safe? Can they multiply if there is only one. I also found a colonstia snail which looked like a sundial, but with red - brown stripes. Is this also reef safe?

I am having a problem with my tank it started with an excess of red algea that covered all my rock and sand. did a water change and sucked that out as best i could. Now I have hair algea and something slimy in the water that is causing my fish to suffocate. HELP!!!!

It can't swim and is carried by currents of the ocean. They have nematocysts and can sting like jellyfish. Although not really practical for the home aquarium because well it can't swim, stings, and ONLY floats on the surface partially exposed to the air. Not 100% sure it can sting a human...

I have a Derasa clam that has a few Aiptasia on the inside of his shell. Right where the mantle comes out. So I can not get to them while he is closed. They are keeping him from fully extending his mantle. Any thoughts, tips and help would be greatly appreciated. Thank you Nathan

Today I stopped up at one of my local stores and came home with a new fish and zoa frag. The fish I acclimated and then headed out for a while. Once i got home I went to dip the coral before putting it in the main tank. I always dip new coral in SeaChem Reef Dip, glad I didn't skip this step...
