identification

This Acropora was sold as a WYSIWYG colony, simply under the label "Acropora Sp." A month ago. A month later, Coloring up Any thoughts? My own best guess is Acropora tenuis maybe?

Won this coral by bid just over a year ago. It was listed as ‘yellow eyed favia’. It was like 1 inch in size when i got it. It grows slow but it suddenly will have a growth spurt sometimes. Its now on a 2 inch plate cause it over grew the one it came on. I realised the polyps are getting bigger...

Got this head of tank cultured ‘bicolour hammer’ from a home based coral aquaculture guy. I swear it has tips like a hammer but they’re small, thin and are so long? Like 1-2 inches long. Anyone have a hammer like this? Its like a hammer had fun with torch lol. It does not open and sway like my...

I’m going on a month and a half of Dino’s. I finally picked up a microscope to help identify what kind they are. Can anyone help ID these? It appears like 2 different kinds. Too hard for me to tell. Thank you

I just noticed this orange glow under the night lights of my aquarium. It’s extremely difficult to get a good picture of it under any lighting. It is located at the bottom of a base rock. it has orange polka dots around a dark middle part. It doesn’t move at all either. Super curious as to what...

Hi, Hi, i’m currently batteling dinos and I was wondering if you could help me id these. Zoom is 250x. My guess is amphidinium small cell.

Ahoy, I added a Duncan to the tank the other day. And when I was on the way home, I looked at the bag and saw a few hitchhikers. Was already planning a coralrx dip so wasn’t really concerned. seems I bumped of a snail or 2 which I wish I would have kept. But I also saw this thing that looked...

Lfs just calls these guys African clownfish. Are they clarkii or allardi? Or something else? Thanks

I had been eyeballing this guy for a while. I have a thing where I will pass fish through many visits and of they are still there they are apparently meant for my tank. The lfs said he was some sort of saddle back but I can not for the love of me remember the name he said. I appreciate it.

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...
