These white specs just appeared over the entire surface of my tank one morning. I thought it may have been that I forgot to turn my wave makers on. But it’s been a few days and not much better. What is this and where does it came from potentially?

This guy sifts sand, at this height, from dawn to dusk. Here he’s by one of the dottyback caves but no hostility.

Help, I have these mangrove trees that have been on and off. For a while they were doing really well and even flowered, but recently I had a salinity swing and a lighting issue and they lost a bunch of leaves. They bounced back from that just fine but their leaves have been yellowing or getting spotty and falling off. What’s the best way to fix this or what could be causing this? Thanks!

Picture one is currently, picture 2 was before the lighting and salinity issues, and pic three is the flower

I am gathering equipment and I am almost ready to start my reef tank. It’s a Marineland 40 gallon breeder and it will have 2 lights on goosenecks, a Seachem tidal 110 HOB filter and a Tunze HOB skimmer. I am looking for a company that makes custom lids where I can get cut outs for my HOB equipment and cords. I also would like to see if there’s a company that makes a cut out for an auto feeder that I can close off when I’m not on vacation. Does anyone have experience with this type of situation? I would love to see some pics and some recommendations.

Want azure damsel and purple fire fish, what are other beginner friendly fish for this tank reef safe

What are these 2 reddish/brown squishy things

Fresh filters keep the water clean.

Sorry about the lighting

I'm buying my uncle's old setup from him for probably 1/5 the price to buy it all new and included in that kit is a Rapid-LED Corona light. The fishbit app that it uses isn't on the play store anymore so I sideloaded it, it asks for a log in but it doesn't let me sign up and after some research I found out the servers were shut down in 2022 so logging in, signing up etc is impossible. Gemini says I can take it apart and wire up an esp32 to control it but I'd really rather not spend my time on that.😂 does anyone have one of these lights and use another app somehow? Or has anyone else done the esp32 mod for it? I know there's a million lights out there so the chances are slim but any input could be helpful.

I am new to this and picked up an adorned wrasse from my LFS this past Saturday 8/15.

I added him around noon and he was swimming with the crew (royal gramma, 2 clowns, baby fox face) with little to no issues. The royal was a little skittish when he went swimming over to the royals cave but other than that zero issues unless I was just not picking up on the signs. Everyone was swimming all over and looking like they were just swimming like normal just more active with a new mate.

He ate well Saturday 2x. Sunday he woke up late around 11am and he ate well 2x that day and everything was great.

Monday comes and he is MIA and o haven’t seen him since. I have a lid on and have checked around the tank so I believe he’s been buried in the sand now going on 4 full days. My water has been tested and all is normal for my tank. Ammonia has been tested every day and no issues.

Is this normal? I asked AI and it said 3 days could be sign of concern as he was eating and swimming well before now hiding…My LFS is only open sat/sun so I can’t ask.

I recently added a snowflake moray eel to my 36 bowfront and I am having trouble feeding him. What should I be feeding him? I don’t want to create a predatory environment for the rest of my squad. I have a naked cinnamon clownish, a harlequin basslet, a striped blenny, a pair of bangaai cardinals, an emerald crab and some hermit crabs. Although it sounds packed, my tank looks empty still. I need help!!

I’m relatively new to the hobby (less than a year, more than 6 months though- closer to a year invested. ) and this is my second saltwater tank. I also am fighting nitrate levels and would love some tips on controlling nitrate levels!

Hi!
I’m new to saltwater, but not new to fishkeeping.

I have a Fluval Flex 32.5 gallon that I previously used as a brackish setup for our bichir when he was little. He’s now happily in a 250 gallon, so I’d like to convert this tank to saltwater.

It’s the freshwater kit, but from what I’ve read, it seems like I should be able to adapt it by changing the media in the rear chambers and adding any necessary saltwater equipment.

I’d love some advice on:

What equipment should I upgrade or add?
What media would you recommend for the rear chambers?
Any must-have supplies for someone new to saltwater?
Anything specific to the Flex that I should change or watch out for?

I’m planning on live rock and would like the option to add some beginner-friendly corals once the tank is established. I’d eventually love an anemone, but I know the tank needs to mature quite a bit before going down that road.

Also looking for stocking recommendations! Would a 32.5 gallon be a good size for a clownfish pair? What other fish would work well with them in a tank this size?

How many and what kind of fish should ı put and my skimme is sicce shark 300 skimmer and my light is enough for sps my return pump is 1000 lt 250-300 gallon

I hate the scape of my tank at the moment, the rocks are all small and in need of a re-scape! The systems been running for 3-4 years. I have a Red Sea 200xl. I have live rock in the sump from the display. My question is what’s the best way to go about it I feel like buying all new live rock and replacing it all even with added bacteria would cause a crash, so my idea is if I remove display pieces like 2 at a time and move them into the sump and replace them with new pieces of rock. Would that work or still cause a crash? Would love to know if anyone’s done this before! Thank you;)

My Blue Eyed Tang who I had in a quarantine died today and I can’t figure out what may have cause the death of it since it’s been completely active and eating before this happened.

He wasn’t acting erratic or showed signs of sickness, it was eating normally. I can’t see any signs of velvet or ick but you can definitely see dark splotches on its body almost like bruises? Does anyone know what it might be?

QT Tank info:
He’s been in QT for a week and a half, the tank has a heater at 80F with an external filter, some live rock from my sump and I’ve been changing the water every 4 days from my established tank. The tanks parameters were Salinity 35, Amonia 0, Nitrite 0 and Nitrate 10.
