coral

Hi there Our neon green tree coral hasn’t opened up in about 4 days and is starting to go black on the tips of its branches. Any idea what it might be? Is it dying? Please help! Thank you

Hi there We have had our Goniopora for about 6 months and at first it was super happy but slowly has started dying from the bottom up. If has stopped receding but the polyps never come out any more. We have moved it around the tank every couple of weeks to see if it likes a different spot with...

Hello! This happens to be my first post/thread on this forum, and am also new to saltwater aquariums in general. I have an 40 gallon aquarium with the measures 12 inches(width) by 36 inches(lenght) 16.75 inches(height) and was wondering if this aquarium size would be sufficient for corals. I'm...

cycling my tank and saw these appear. Can anyone identify them? Doesn’t look like algae because it has a base connected to the rock. Is this a good thing or bad thing? Haha

I Red Sea Max 250 that has been running for about 5 years now and I have always had some issues with algae/ high nitrates/ high phosphates. I do regular water changes but my corals have never seemed to really do that great. Most live but never have great color. I have been following some forums...

So im really curious of this Golden Leopard Paly. I have never heard of it. And i saw the asking price for one polyp was insane! So i was wondering if you guys could give me sone insight on this coral.

Hello, I'm not sure what it means, and I can't find anything on it anywhere. My glove/ clove polyps (not sure which they're called- seen it both ways) have been closed the past couple of days and were not looking too well. I have no idea why. There's a couple of stalks that have shriveled almost...

So, in the Marinetank, there's something around one of the coral. I don't know what it is, I'm scared that it could harm any of my sea creatures. Can you identify it? I can't find anything that can help me by researching either.
