white spot

I know this isn’t the greatest photo but Pennywise the clown fish is very active so it was hard to take a decent photo. He has a little white spot near his tail and I was wondering what it could be. Like I mentioned, he’s very active, comes to the side of the tank when I’m there to feed them...

We bought this “emerald crab” today and just want to confirm whether or not it is actually an emerald crab because it is not green like most of the pictures online. We were thinking that maybe perhaps because it is juvenile that it hasn’t turned green yet. Also when we got home we realized that...

Hello Reef2reef community! I wanted to start a thread pertaining to a research paper that I found online about C.irritans and a potential treatment option. Here is a link to the document -> https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6344632/pdf/AEM.01982-18.pdf In their abstract, they...

Hello, My clown started developing white edges on its tail fin 2 weeks ago. I cant tell if this is a disease or if clowns develop new patterns. I only have the clown and two turbo snails in a 30 gallon tank. All my parameters are where they need to be and I do weekly 15% water changes. Ive had...

Hi, I recently picked up some corals off a friend and this random mushroom was closed and tucked on the back on the rock. He came loose and floated around until i caught him & put him into my loose mushroom cup. he eventually attached to a rock. Now that he’s open I got a semi decent picture of...

I noticed two white spots on my Blue Cheek Goby approx. three weeks ago - he's doing fine, no further spots have developed and no other livestock show signs. Would love to get him out to treat and quarantine but catching him is near impossible with my size of tank. What is the current recommend...

Hello yesterday one if the heads had a small white dot. Didn’t think it could be anything. I’m new to Euphyllia so I’m not sure if this is normal. Today I looked the white spot is bigger and another spot popped up on another head. What is this??

Hey all, Pretty new here and just noticed today this white spot on our Chromis' head. I just added a bubble tip anemone today, is it possible it is a sting? or something else? Tank is relatively new, water parameters have all been consistent as we've added fish. He has been in the tank for about...

Hello, This is my first post I have a cbb for one month in qt. He has no problem eating. Day one was a full dose of cupramine .58 and prazi for 2 weeks. Then a water change making sure the copper didn't drop. Water temperature 80 degrees. There looks like white spots or sores on the scales to...

Any ideas of what this may be? He doesn't appear to be sick, he's a finicky eater but is demolishing all Majano anemone.

So I have a coral beauty that has recently grown this white spot on its eye. I couldn’t get any pics to show well so I took a video. Also, I recently put a fire shrimp in and the angel is OBSESSED with it! It is constant swimming into the shrimp begging for some attention. Is this stressful to...

Hi guys I'm relatively new to the hobby and that's my first thread here... looking for some help to identify what is on with my Yellow Tang. Since a week I had my baby Yellow Tang that is about 2 inches now, I noticed a little whiteish spot on his dorsal fin. A month has passed now, and it...

I have had this tomini for about a month now and he is an absolute pig. When I got up this morning I noticed he had a white spot on his nose. It kinda looks like he scrapped on a rock maybe. I added a foxface last night and the tomini has been pretty interested in him, so could them chasing...
