coral

I’ve had this hammer coral for a little over 2 weeks and for the past 2-3 days it’s been closed. I’m not sure what the problem is. I’m guessing it’s flow but I’ll list my parameters for the 15g it’s in. Salinity 1.023 Nitrate 9.0 Phosphate 0.04 Alk 8.0 Temperature 77-79

Hello, so my entire tank has been doing great outside of this one hammer coral. Have only had it for about a month and noticed about 2 weeks ago one of the heads has died. It is now going to 2... any ideas whats going on? I have a peppermint shrimp that i notice picking at the head but it is...

Hello, My duncan coral took a rough turn when the algae on my lid blocked uv light from getting to it for a couple weeks. Based off the looks is this frag recoverable? I fixed the lighting block issue and the tank has plenty of lighting. Zoanthids, xenia, and bubble coral are doing fine.

So I’ve had a 29gal mixed reef for about 5 years and I bought a house so I’m ready to upgrade. Planning on getting 190gal 60x24x30. What do you guys think the best wavemaker for a tank like that? Mixed reef some sps and deff torches and hammers too. Also what strength flow (got) do you think...

Is this too much flow? Just got it!

I'm brand new to saltwater, and after cycling for over 6 weeks, I purchased (Petco) and placed my first round of "livestock". I started with a clownfish, an anemone, a hermit crab, a turbo snail and a coral frag. All seemed to be doing well, until I got the bright idea to (carefully) relocate...

Not much to go on lol. I bought a tunicate rock and had a couple coral hitchhikers on them. Wondering what they might be, I believe the rock comes from the indo pacific, but likely indo specifically. Mostly wondering what the coral in the circled photo is. Considering what I believe is a favia...

Hey guys! New here, looking for some help in saving our trumpet coral. It seems to be slowly dying. I’ve checked all the levels. Everything seems to be normal. We have led lighting. Any advice is greatly appreciated.

Bought this coral listed as some sort of euphyllia at LFS. Was wondering if someone can ID it further. Looks like some sort of frog spawn/hammer cross

Hey everyone! I’m Darren (37/M/Toronto, eh) and I’m excited to be joining the reefing community! I’ve always been fascinated by the ocean and the incredible ecosystems that thrive within it. After some research and a lot of learning, I’ve finally taken the plunge into the world of reef tanks...

Found this coral growing on the back of a snail’s shell. Store had it labeled as “ninja star astrea snail”. Quick search resulted in nothing about them being captive bred, and since they’re native to the Atlantic. This leads me to believe the coral is some sort of Atlantic sps. Can anyone chime...

Upgraded from a 30 gallon to 75 gallon, and my Duncan is thriving but for a 3 weeks now my frogspawn has yet to open up completely. Any thoughts?

What is this long tentacle next to my orange or peach hammer coral is that torch coral or frog spawn hybrid?

Hey everyone, Just seeing if anyone has tips or a video tutorial on removing a zoa colony from a piece of rock. Like is there a way to gently peel them off? The piece of rock this colony is on is always getting covered in algae and has a few aptasia living in it, that's why I would like to get...

i am looking for good corals/fish for a nano tank that will do good with each other. For the corals i´m looking for something with a lot of color while for the fish i don´t mind what they look like.

Okay so, I have 1 nicrew led gen 1 150w light and i wasn't sure if I can use this light and the new gen one at the same time, would it be compatible in the sense of lighting specs? I bought the nicrew in November because I was preparing for the 55 gallon. But they discontinued it. I do not have...

So I’ve had my tank for about 4 weeks now. It’s all cycled and I added a clownfish pair around 3-4 days ago. I want to start adding coral so just wanted to ask if I should wait longer or just try my hand at some of them? These are my parameters currently(albeit 2 days old).
