My gen tang didn’t have this yesterday ! Hope this is just an injury

I have just installed the classic 110 int OCTO skimmer I currently have it running with the valve completely open, I read I should leave it like that for 2-4 weeks so It can break in. Is that correct? Should I leave it open for the 2 weeks or do I adjust the valve sooner what should I do what...

Hello everyone, I am new to saltwater. It would be great if you people could help. I got the Clownfish on the 8th of April. Turned on the new skimmer on 12th april. Just after turning on the skimmer it created a lot of lot of microbubbles and it was released in the tank by the return pump. So...

I need help with my sump should I stay using filter floss on the top layer of the cups or should I replace the 1st cup with a filter sock(i’ve been hearing it was better). Or can I have a combination of filter floss for the first layer followed by cup 1 as a sock filter and the other cups as bio...

Help I’m thinking about buying a protein skimmer for my 55 gallon tank. I have a sump and I did all the measurements for the skimmer it would fit tight with enough space for the pump to function, and collection cup to be cleaned. but I’m wondering if it’s too much for a 55 gallon tank or if I’m...

I have a question about wet/dry and sump. I have both and was planning to use them.. in the sump there will be a refugium and a protein skimmer. Is this overkill? It’s been awhile since I have done this, so be kind. 😂 It is a 125 gallon aquarium with 5 gallon wet/dry and 29 gallon sump.

I just saw my torch coral and this is what I found!! Can anyone help me in what to do or what? Because that part that hanging down is all meat not just pure skeleton

I noticed today that one of my clowns has slight damage to the fins, slight white spots on some spot of his body (Pretty small) and his eye has started to be cloudy compared to the other eye. I'm wonder if this sounds like a bacterial infection. It is also important to note that recently my...

I’ve had my small 20 gallon cube running well for a year and everything has done amazing and growing, but over the last couple of days a couple of the corals have been unhappy. My Goni and hammer won’t open, and the foot on my hammer is getting smaller. Also one of my purple polyp corals won’t...

Anyone know if this is a Sherman or Black Widow anemone, 2nd and 3rd picture's tentacles should are red in person

When I was taught the basics a couple years back I was told 76°F was the only acceptable temperature for a reef tank, so that’s what I’ve kept my tank at this whole time. However, the guy who trained me at that previous LFS job was very set in his ways. I often hear 78°F is the best, so I’m...

I recently bought a new hammer coral a few days ago and put it in my tank. I’ve never owned one before, so I don’t know much about how it specifically look at this stage.

its been fine for 3years now and has survived when my other corals like torches died off but now it's randomly melting?.

Hey all I just got this pair of clownfish on Monday and this one is swimming weird and always swims on top like that(idk why my camera didn't want to focus) he is still eating and interested in food some I'm not sure if I should be worried or be doing something to help. Thanks in advance!

Started my reef today. Need help IDing these anemones since I don't really know the different kinds yet. They don't look like the photos I have seen images of aiptasia and majanos online and they do not really look like them, but I can't expect these to be anything but those. Posted earlier but...

Hello! I hope you are haveing a good day! I have a 75 gallon saltwater tank and about once a week a fish will start laying/flopping on the bottom and dies. The tank is about a year and a half old. The tank had 4 clownfish(they came together and don't fight), 1 coral beuty angelfish, 1 longspine...

Help. Wednesday (2 days ago) my husband screamed 'come in here fast' and I ran to my 120 gal reef tank. My anemone was being attacked by several very large copepods. They were literally playing, what can only be described as a game of tug-a-war, with it's tentacles. I quickly scooped him out...

Hi all so I have a 75g tank and I bought a bubble top aenenome about 6 months ago and anthelia 2 months ago. Since then my aenenome disappeared, then the corals shrank smaller and smaller and now they are just stalks. I narrowed the problem to a broke salinity measurement. I was at 1.017. For...

I haven’t had any fish/coral additions to my tank for at least 4-6months now. My fish have been very healthy and eating well, but suddenly noticed these spots/ white cast develop on the body of the clownfish. Any identification would be great so I could determine the treatment ASAP. I have 37%...

Got a new coral 2 weeks ago, pet shop gave it to me to free up space, called it a 'lord brain' but couldn't tell me anything else on the name or species. Went away for a day or two and noticed when I put the light back that there's a bleach ring around it. How do I get it to recover?

I have a small 3 gallon pico all coral tank on my desk that’s been up for about a year with no issues at all until about four days ago I noticed some coral missing, I kept watching thinking since it was just my tiny bit of pulsing Xenia it was whatever but when my green hairy mushrooms in the...

Hello. I have a 15 gallon hello reef fully stocked with zoas, yumas, mushrooms, target mandarin, opossum wrasse, and pistol shrimp. I'm running the AI blade grow and glow. I've added pods several times because I never see them on the glass or backwall. Now about once a week I get a 'bloom' of...

Hello I have a 55 gallon cube and I was away on the weekend for my sisters wedding. I come back today and my tank is a mess. Would an anemone dying cause a crash I have a lot of livestock and filter and skimmer. My flame angel I can’t find (super torn about this) watched my clownfish die, dead...

My clownfishes belly is swelling up and he keeps floating up toward the surface. He did still eat if that means anything (he normally swims a little funny as he is missing a fin but this is different) I’ve never dealt with anything like this any ideas?
