I just got an emerald crab, and now I'm worried for my coralline algae. Since the emerald crab left the bag he has been picking at my live rock non-stop. I understand that they are grazers, but this guy is insatiable. Will the algae strike a balance with the crab, or am I doomed to bare rocks...

Thanks, mr_X. I spoke to the LFS, and the macroalgae they sell is chaetomorpha. I will probably pick some up tomorrow evening, and I'll try to be patient with the algae blooms. Right now I also have a 'pod bloom (I can't tell whether they are amphi- or cope-pods). Pulling the foam filter out...

Since my original post, I have swapped out the last of the basic aquarium fluorescent tubes for an actinic bulb. The compact fluorescent household light just kept falling off the top of the tank, so it is gone (it was precariously balanced). I think everything is content, if not rapturously...

After many years of keeping fresh water tanks, I decided to try a salt tank. I intended to clean out and use a 20 gallon tall that was set up as a terrarium (I moved my leopard gecko to a new tank recently). In the course of cleaning the tank, I stood up from a kneeling position with my hand on...

Thanks for the IDs. It's nice to know that our live-rock freebies are something that people buy individually. I don't know how well it comes through in the pictures, but their coloration is almost identical. My wife and I suspected that they were larger and smaller examples of the same species...

My wife spotted these on a piece of live rock at a local store, along with a mushroom coral. We bought their rock, and now we're wondering what these things are. When we put them into the aquarium, the smaller one swiveled to face into the current. Does anyone know what they are, and how I can...
