white

Hello everyone. I have attached 3 pictures of this white stringy stuff that appeared two days ago in my tank. I assume it is bacteria? Can anyone confirm or correct this? Thank you!

Hello, I have a 9" Dejardini Tang that I need to re-home. I was given it by a local fish store due to the HLLE. It has got a little better but still there. It was fully QT utilizing Copper, Metro, Molly tested, etc.. and used to be in my big tank which has no parasites. Also, to mention, my...

Hello everyone, i noticed this stuff growing on the flesh of my Trachyphyllia. Is this a sponge? Because if you zoom in, it kinda looks stringy, like a ball of nematodes or something. Thank you all in advance

I have had my White Tail Tang for roughly a month. About a week in, I noticed a small white patch form on his side. Over the last couple weeks, the patch has gotten larger and looks to be raised off his body. I’ve also noticed a second patch forming on the opposite side, near the bottom of his...

I am dealing with something in my tank that I can’t identify. It looks similar to GHA but is white. It flows similar to GHA & comes off objects easily with a toothbrush. It is invading my tank and is killing my corals. It appears to creep up the base of the skeleton and maybe suffocate the polyp...

I recently purchased a nice purple nephthea coral and just now noticed these white tentacles that have grown from the rock since I got it. I don’t remember seeing them when I put it in the tank so I’m pretty sure they’ve grown over the past month. Very curious as to what these are/ this is?

Hello, Just noticed this today. Any idea what this could be? Should I remove asap? Total size is about 2in wide 2in tall. Thanks

I have a Hipargero 100w 5 channel spectrum light for my aqueon standard 29 tank so it’s 18 inch tall the tank. I have mixed corals, torch, hammer, birdsnest, zoa, acan, gsp, Duncan… when I set up the light schedule, for the full ramp portion, I can choose the percentage of each color spectrum...

I just noticed these sponge like things pop out and didn’t think anything of it, but since I’m having dwarf seahorses/very sensitive fish in this tank idk if I should keep or get rid of them theyre white tentacles

This white translucent mound popped up overnight. Tank is well established, without any major issues for the past 2 years. Any ideas? It seems rigid and sprouted from one tiny stem like branch. There has been no change in size over the past week.

Have had these in my tank for a little while now and haven't been able to figure out what they are for sure. They're white and black stripped and like to collect around this coral and I'm not sure if they're benign or something I should be removing. Here's an image, please ignore the turf algae...

Hello all, Hoping to get some advice. Just received an order of fish that included an Algae blenny, Tomini tang and a few other smaller fish Everyone has been in a quarantine tank for 3 days so far. Just noticed a wound on the tomini tang and not sure if this could be uronima or a bite from...

Hi all, I purchased a new fish yesterday, thinking it was a 6-line wrasse. It is not. Any help on the ID would be appreciated! White body with lateral black lines, 3 per side. Dorsal fin also has black lateral line. Some black spots at rear coming from the lowest black line. Head and neck...

How rare are white tangs? Video from a snorkel off west coast of big island Hawaii yesterday, filmed just as I was getting out in the shallows - completely white ‘yellow’ tang with slight yellow tinge to fins, swimming alongside its true yellow family!

Hi, I’ve noticed that my starry blenny turns white everytime after he eats. Besides that he seems fine, been in the tank for 6 months. He eats like a pig but everytime after feeding he seems in distress. He starts breathing very fast and turns completely white for like 30 sec to a min. After...

every night around this time(a couple hours after my whites shut off) my clownfish starts going crazy. Swimming fast back and forth in the tank and looking like he is eating. I sometimes have micro bubbles when I need to top off my tank so I just assumed this was always the case. Well tonight...

My Galaxia just recently started looking like this. Is it a definite goner?

Hi. This is my first post on reef2reef. I normally browse but never contribute. Iv just discovered a white substance which looks gooey behind some of my live rock. I spend quite a bit of time admiring my tank so I feel its appeared quite quick. Everything else in my tank seems fine. All my soft...

I recently downgraded my tank and after a few months I've noticed that my red sea lettuce (?) has not colored up since the move. It appears to be slowly growing, but very pale. My dragons' breath algae is doing well and I've had it for less time. I assume the change may be because of the new...

Here is the goby's poop and the microscope pics show the white part of it. Can't believe he pooped all this out at once... (Vid at bottom) 1. 2. 3. 4. (Video) filmed at 100x and 400x https://youtube.com/shorts/vmXGkAn8VaE?feature=share

Hello! Since some days ago I’ve noticed that there are some of this thin white worms attached to the glass, sometimes they hide on the sand and when they’re near the water flow they unnatach and float around the water in a crawled position. I leave a video and some photos to see if anyone knows...
