Is this shell part of rock

[fishygrrl]

So I'm cycling this aquarium and only have live rock and rock but it seems the shell has opened and closed on occasion. When I purchased the rock I thought it was just an old shell part of the rock. Is the green okay on the rock? Could this shell possibly a home for something?

If the rock has been kept live, the clam is probably alive too. Or only recently dead.

Hope I wasn't supposed to feed it. Is it ok just to leave there? How do you normally know if they are alive. We saw it open a few times and I added some dry rock and found it closed today

Not sure it would live the 30 minute drive from the store

Did the rock dry out completely on the drive home? I've had rock shipped three days only kept damp and lots of things survived on it.

It was damp. Taken from a reef a store was taking down. We placed it in a cooler and they put some paper over it. I placed it right in the water.

So about thirty minutes of air maybe but it was damp when I placed it in my aquarium.

Lots of things probably survived. They'll start to show up once your cycle is complete, which shouldn't take long with that rock

Do you know if that green color on the rock is ok? I had saltwater for maybe two years but I'm finding I forgot a lot of things.

Also, I want some easy coral at some point. Before I never tried and probably made a dumb mistake of over stocking. This time I'm trying to plan just a few fish or shrimp and some coral or things

It just looks like algae. Keep the water in check and it won't be a problem. Xenia is fairly easy. That was my first coral and now I can't get rid of the stuff

That is how it looks so far. Will water changes keep the algae down? Unfortunately there is not many sun free areas so I may battle algae a lot.

 

[herp_mommy]

The sun will definitely play a part in it. But as long as you keep the excess nutrients in the water down it should be well controlled.

 

[fishygrrl]

I hope. I don't want to kill everything.

Any tips on keeping nutrients down?
