I’m feeling a bit, defeated with my fish choices for my tank. I got a Splendid Dottyback and it bullied my Watchman Goby. I took the Goby out so he could recover for a few weeks in private. I took the Dottyback back to the LFS and asked if there was a more peaceful fish I could add. They...

i went to remove my wave maker to today for cleaning and found this strange mass in the corner next to it, almost looks like a egg sack of some sort but i have no clue what it would be from.

Hello Everyone! My first post on here and it comes with a worrying situation! The tank has been running for 5 years now with minimal issues thanks to all the advice on here! However! I added a large copperband butterfly about 2 months ago as the only new addition and over the last few weeks...

Hello everyone I posted a thread regarding this angel before as he has flukes but he was in QT and healed for 4-5 weeks and I made him fat before transfer into QT tank. I am assuming he doesn’t have flukes as I did two rounds and his fins healed up etc and he isn’t breathing hard or rubbing and...

I have a Red Sea nano max xxl 52 gallons tank. Nano mat and protein skimmer. I bought this coral 5 days ago. The tank is about a month or more old. It seemed very happy the first 3 days and then up to today has been barely extending polyps and shrinking in size. I checked my parameters and...

So this has been puzzling and frustrating me for the past few days now and sadly I cannot find a lot of information online about it... I have a Neptune Apex and use Kessil LED lights on my tank. For years, I just had then run on a table that I would manually adjust over time as the sunrise and...

Hey guys, I'm struggling with KH. I have a new 220l system with 2x clowns and 2x cardinals, 1 anemone, small GSP frag, one ricordea, 2x hermits. My LFS pointed out that my KH was too low and suggested Fauna Marin Elementals KH solution. I've been dosing it for a while but can't seem to get my KH...

He fell under my hammer and I didn't notice for a couple of days. What should I do?

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?.

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...
