identification

Hello all, first post and first tank. While I have a bit of experience maintaining other's tanks, this is my first personal tank. Any and all advice is welcome It's 27 gallons(or so I was told), and has a 3 chamber filtration system in the back. Standard cube tank from what I've seen, and I am...

I recently inherited a saltwater tank with this coral in it. The previous owner did not know the species of this particular coral. Its health has been declining over the past year, and I would like to know what specific coral it is to determine how best to take care of it going forward. Thank you!

Found dude bro in my tank. Not sure what he is, if he’s harmful or what he eats but I didn’t put him there and my puffer is very interested in him. He took a couple bites out of him in the video. But he has tiny little black eyes and what seems like a hard back the puffer couldn’t bite through...

Found this little guy while dipping my newly bought Trachyphyllia. Can anyone confirm if this is gorilla crab or any other species? He is very small, body is ~5mm in diameter.

Hello! I received this skimmer from an acquaintance and it looks rather old. However, since it was free I’d like to see if I can use it. I’ve noticed it is missing some pieces. I haven’t taken the time to clean it yet either. I just want to know what model it is so I can see if I can run it on...

I know the picture is not great but its best i could get, anyone have any idea what this is growing on my frammer (pretty sure its a frammer). What im refering to looks florescent in my tank.

Hey Reef2Reef! A friend of mine gave me this frag and it’s getting a bit big now but we still aren’t sure what coral it is. Could anyone ID it for me please? Some people have mentioned it’s a Fanta Orange Chalice but not sure. Your help will be appreciated!

Hi everyone , just got a frag from Petco today that they didn't know what it is. I'm thinking a rhodactis and maybe sunset but I'm not sure, have not found any image online matches it yet. Any ideas ?

Can anyone id this clown for me? I would appreciate the help

Noticed this on my zoanthid puck. It's a new addition.

Hi, I've been having trouble managing this algae ever since I added a new piece of live rock to the tank. It started growing on the rock and I've been trying to manage it by manual removal, but it just keeps growing back. It has spread into parts of the sand and has started to creep up onto the...

I'm not sure what this SPS is called. I dropped it when I was cutting the plug stem off and it broke into half a dozen pieces. Since then it has started encrusting and growing pretty quickly. Pinkish skin and light blue polyps. I'm sure it's nothing exotic but I have no idea what to call it.

Just noticed this baby anemone in my nem tank. It was mostly closed with tips of tentacles poking out when I first noticed it. Then of course I messed with it, it completely closed up and it must know I’m trying to get a pic, cuz it hasn’t opened up at all in an hour. It’s currently about the...

I live in Northern Canada and the nearest Saltwater store is about 7 hours away, so everything we have gets shipped. We cross our fingers and pray things survive shipping. That being said mostly everything usually does survive. Almost all shipments take 3 days to get here with FedEx priority...

Hi all, I suffered a prorocentrum bout a few months back and it has come and gone in a few patches since, but now I noticed this red stringy stuff that eerily looks like an increase in Dino. I put it under a microscope but I couldn’t really identify anything. I attached a video! #reefsquad

I noticed this on the rear of my tank last week while doing a water change. At first I thought it was a snail. This week, still there and no movement. Is this just something stuck my tank or something growing?

Can you tell which type of clownfish these are?

Could anyone ID this for me please? I’m guessing it’s a soft coral but maybe not?

Hi there, I purchased this LPS coral over a year ago as a Scoly but I’ve never seen one like it since and it’s very different with its feeding response compared to my War Paint Scoly (which definitely is a Scoly). Any suggestions welcome!

Hello there. If anyone can help identify what this is on my glass. It's not air bubbles. They seem to be swaying and sticking to the back of my tank. Also note that we have added trigger pods about a month ago in the back of our AIO tank. Tried getting a better picture in clearer lighting but...

Hello I got this encrusting coral a few weeks ago and it seems to be growing really well. However I’m not totally sure what it is. I asked the associate at my LFS if it was a monti and they said no. But they couldn’t think of what it was at the moment. I got it on around Feb 7 and it has grown...

I just got a platinum clown yesterday to pair with one of my clowns, I was looking to buy a platinum even though i love White Wyomings because i thought percula would pair up better with another percula as my attempt at pairing a percula and a ocellaris went a bit meh. The male did the shake...

Hello everyone If anyone would be kind to help us in our new tank. We have had it for 2 months now and just last week this showed up. We can't get our hand on what it is exactly. We have caribsea Life Rock and life sand Ammonia - 0 Nitrite - 0 Nitrate - 20ppm Lights are on for 6 hours We do...

I’m servicing a clients tank and they have these small aphasia looking things everywhere with an unusual (pretty?) coloration. They seem resistant to aptasia x. Historical pearlscale butterflies will eat them I’m told. Anyone know what these are?

Had a bunch of these growing all over my rock when I got the tank second hand. Pruned all but one away a year ago. Now wondering if it’s actually sinularia like I assumed. Is it Japanese pink mepthea? I love the color and growth pattern. The id would decide if I frag it or not. (Note this is my...
