Hi everyone, Does anyone know the species of this SPS? The owner of one of the lfs said he wasn’t sure what it was but it was super hardy (not sure if that helps). It’s my first venture into SPS and I wanna make sure I get it right. Thank you and Happy Reefing!

Need some help with what this orangish brown algae is and how we can fix it..if we need to? Tank is several years old, nothing has been added recently other than water for a water change. Seems to be spreading all over everything..

So I noticed my clam was closed up today and upon further inspection I see these little rust colored what I assume are flatworms on it. Are these cause for concern?

Anyone can ID what type of Xenia this is? It was pulsing in the greenhouse when I bought it and when I first got it in my tank. It's been there 2 weeks now and hasn't started to pulse again.

Hello, New to the forum, so I’ll give an overview of my experience and self. I’ve fully immersed myself into this hobby for about three months now. I guess it was just a hidden passion that I had no idea I had. I am in the Navy! I’m stationed in Okinawa, Japan and am very close to the ocean...

Spotted this fleshy bubble looking thing growing from the skeleton on my torch. It’s the same color as the torch so I know it isn’t bubble algae. The pics aren’t the greatest but it’s glued down so it’s the best I can do for now. Any help on the ID would be appreciated.

I bought a coral from a place that only sells coral. My dad thought it would be cool to buy this and the employee who worked there said "its easy to care for". I don't know the name because my dad is the person who bought it. Can I please have help identifying this coral? I was thinking it was a...

I have red algae that looks like a slime coating and also has long hairy strands. Is it beneficial, or should I get rid of it. If so, how? I attached a few photos. Thanks!

Hello all you cool coral people, Need some help identifying these 4 corals, Genus name, species if you know it! I am a college student helping my local fish store to identify about 100 corals and it’s down to these last few. Thanks a lot!!

Hi! So my local pet store has this coral that i think is neat. It almost looked like SPS in real life, but I believe it’s a soft coral because that’s all they ever carry. It’s really cheap and I love the look of it, but can’t figure out what it is so I can see if I even want it in my tank...

I have these to hitch hikers, 1 from a rock, and another was on the base of a Kenya Tree I bought. Just want to make sure both are safe and okay to have in a tank as well as what type they are. Sorry for the blurry pictures they are very small.

I got some Xenia about 3 days ago, and it’s pulsing moderately Bc it’s in decent flow, and it is opening up which is good, but I can’t help but notice a lot of the feathers are black? I’ve gotten some conflicting info on this, with people saying it’s a phase while some saying their Xenia’s...

Hi All - I recently received a few corals from a fellow reefer and have had them in my tank for two days now. I have some idea (based on googling pictures) of what these are but would appreciate if anyone knew exactly what these corals were! Thanks in advance

Hoping all you fine people can help me out and let me know if this is aiptasia on the left side of this frag? It looks somewhat different from pictures online.

I've had my tank for about 1 1/2 years, never had any problems. I have a rock flower anenome, spiny star snails, blue leg hermits, clownfish and an short spines urchin. My pump transformer exploded about a month and a half ago. Killed my emerald crab, shrimp, zoas and I've had problems ever...

Have some snot on the back glass, that's growing in an interesting pattern. It's ONLY growing on the glass, and both the turbos and nerites are eating it, so I don't think (fingers crossed) it's dinos. Some of the strings are nearly a foot long, but no bubbles. Where it's growing best is on the...
