TatorTaco Posted January 14, 2021 Share Posted January 14, 2021 Welcome to nano-reef.com! I hope you'll stick around to learn that we are a friendly group with lots of great information to share. Please be sure to review the stickied posts, like this one, which will likely answer every one of your ID questions. Below is my lazy attempt to ID. Yellow is an asterina starfish. Purple appears to be some sort of (harmless) filter feeder. Blue appears to be a majano anemone. Quote Link to comment
Anthony2.0 Posted January 14, 2021 Author Share Posted January 14, 2021 Thank you and do you know what the flat one is in the other photo? Quote Link to comment
Tired Posted January 14, 2021 Share Posted January 14, 2021 Could be some sort of bivalve, like an oyster or clam. Quote Link to comment
Anthony2.0 Posted January 14, 2021 Author Share Posted January 14, 2021 Thank you I see something inside but I don't see it move or anything Quote Link to comment
Tired Posted January 14, 2021 Share Posted January 14, 2021 If you tap it, does it close? Quote Link to comment
Anthony2.0 Posted January 14, 2021 Author Share Posted January 14, 2021 It does but it doesn't open very wide Quote Link to comment
Tired Posted January 14, 2021 Share Posted January 14, 2021 Clam or other bivalve. They don't open very wide because they would expose their guts to things. Clams don't work like they do in cartoons- they open just enough to filter water. A gaping clam is a sick clam. Quote Link to comment
Anthony2.0 Posted January 14, 2021 Author Share Posted January 14, 2021 Oh ok thank you very much I have a better picture of it Quote Link to comment
Tired Posted January 15, 2021 Share Posted January 15, 2021 That's absolutely some sort of bivalve. It doesn't really matter if it's a clam, oyster, or what- all the ones that are shaped like that are about the same. They filter-feed tiny particles from the water. In some tanks, they do fine on their own. In others, particularly newer tanks, they run out of food and starve. You can try feeding it and any others phytoplankton, if you're set at all on keeping it alive. If it ever stops closing its shell on being disturbed, it's dead- it should always shut if you do something like firmly tap on it. Quote Link to comment

Tired Posted March 21, 2022 Share Posted March 21, 2022 Looks more like a majano, though hard to tell in this photo, and this post is over a year old. Quote Link to comment
