r/saltwateraquariums

Unsure about what type of worm this guy is but noticed them crawling around in the sand bed/along the glass. (Cup is dirty water from a frag we just brought home from LFS not our tank water). Any idea if it could be harmful and suggestions on how to get rid of them? Mixed reef tank with anthias, clowns, goby & box fish. Initial thought is adding a rass (we have a 3in sand bed) but worry about aggression with our juvenile box fish. Thanks in advance for your guidance!

Hey guys, yesterday I bought a blue pulsing Xenia online, it took a day to arrive, and when I opened up the bag it reeeeked, it smelt so bad so thought it was dead, but the frag actually looked okay, I acclimated it and put it in my tank but it's soooooo droopy I'm worried that it's dead. Ist pic is when it first went in the tank, second one is today. (All of my water parameters are perfect)

I have a handful of large fake coral decorations that I had in original 90g set up about ten years ago before I got into reefs. I was doing some cleaning out of my equipment closet and figured they be good use to someone else as I only have reefs now. I bought them from a premier saltwater store in Pittsburgh directly out of their fish only display tanks. They are pretty large and completely solid and heavy. They told me they were hand built by one of the best builders in the country, but I have no idea who. The largest one was an elk horn style but ended up getting broken many years ago. I paid somewhere around $3k for the whole lot. Not sure if I got totally taken when I was a noob. I was thinking somewhere around $100-150 for the small ones and I’d like to get $300 for the big ones.

Called Waterbox yesterday and they said my tank should ship out sometime in the next week or so.

I really hope they’re telling the truth because my 10 gallon QT tank can’t really hold much more coral and Reefapalooza is coming up. 😭😎

Anyway, thought I’d finally post something rather than continue to lurk and this update is my excuse.

came home from work and my red bubble guy looks like shit and is secreting some kind of mucus, also the tank is unusually cloudy out of nowhere. I’ve been pretty conservative on feeding so Id be shocked if it’s regurgitating food. Is this thing dead or what.

‼️there is a peice of live rock behind the dry rock to the left‼️Im getting another wave maker that’s good for nanos I just need to know if its an urgent thing or not ALSO these r not the same Xenia you’d get in America there Australia Xenia and blue Xenia there not as feathery as normal Xenia

Well I don’t know if it’s a midlife crisis or my jobs just gone to hell the last year and I wanted a new hobby to engage my mind positively, but I always wanted a saltwater tank - on and off the last 20+ years. So I finally decided wth I was going to do it. Spent months of research bc that’s just me. I decided with my low confidence probably a waterbox AIO system would be best. Got a 50 gallon bc I wanted it upstairs and was concerned about the weight and location although I would’ve liked slightly bigger for certain fish.
Got 2 AI prime 16HD lights, 2 AI Nero 3 pumps, Sicce syncra silent 2.0, 2 100w titanium heaters with inkbird itc-306a wi-fi, tunze osmolator 3 with 5 gallon reservoir, kraken mesh lid, brs 5 stage 75 gpd ro/di system and all the stuff with that - a heater, a pump, 2 food safe trash cans etc.

Anyways took 4.5 months of getting the waterbox tank then several weeks setting it up. Had to install a new outlet in the location it was going bc the spouse threw a fit with it upstairs. Now it’s downstairs and it’s ok there but wish I had gotten a slightly larger tank.
Anyways I’m a newbie and read a lot and watch a lot but have no clue what I’m doing. The local fish guy sells live Bali rock so I got that although very expensive. Then I cycled. Numbers were good so I went to get my clownfish. I got a bonded pair that had been there since June. I go there a good bit and know they were there and looked fine. The female went easily into the catching cup but the male would not. The guy even had a hard time getting him in the net. Eventually he did and we went home. I transferred them into a larger bucket and then acclimated them about 30 mins. I will say the male got stuck for a few seconds in the plastic bag. I guess I poured them out too slowly. Anyways I put them in the tank after acclimation. Female looked fine, still does - although I’m paranoid. Male kept to the bottom then went up to the outlets for the return pump. Hung there for awhile. I went to bed and found him dead under one of the rocks. I took a sample of my water to the store and they agreed all nos were good and just said sometimes they get stressed with transfer. Said they’d order another that matched- it was a fancy type. Anyways any clue on what happened? Any advice going forward? Guy at the store says come in two weeks for 2 gobies (different varieties) with pistol shrimp if everything looks good. I’d like to eventually get corals - want things that are hardy though.

I haven’t checked my numbers, just curious if the algae is good or bad. Thanks

He was moved to a bigger tank in a place where I can actually see him while hanging out on the couch. Turns out, he goes for a swim each afternoon!

Like the title mentions I'm a complete beginner when it comes to the hobby. Never had any fish, fresh or salt water, this is my tank it is 2 months after nitrogen cycle.

It is the Waterbox AIO 35.2. Their older PLUS EDITION (they have a much better updated one IMO) I'm not currently dosing. I use instant ocean Reef Crystals, it's not the best from what I gather but it's available at my local pet store I can get an emergency supply if I need it and Amazon always runs deals and of course free 2 day shipping.

Equipment: 2 filter socks, sponges, ceramic, activated carbon, a sicce shark skimmer 150, sicce return pump, scuba Preset heater(will upgrade to inkbird and titanium eventually) AI light Prime 16hd, Ai nero 5 powerhead, waterbox mesh lid and nature dimensions ATO with a 5 gallon rodi water bucket. I also got rodi for the house.

I do a 5 gallon water change every week and test daily.

what do y'all think? I'm posting to get tips and constructive criticism specially on my coral placement.

sooo i can finally show of my first ever tank livestock!!! i posted here a while ago - now my tank is fully cycled, parameters are stable and after some consultations with PROs in saltwater tanks i introduced these guys to their new home! i also added another live rock, because i wanted to provide my shrimpy fellas with more place to hide, as well as creating space for possible corals in the future. i gave names to my saltwater friends (ik it might seem childish, but i got a bit attached to the rescued shrimp and their new tankmates hah) - the big shrimp is bobo, the small one is lobo, snails are nascar (they’re fast af boy, all i can see them doing is either chill in the sand or run around like crazy) and well, tectus is just tectus lol
i thought of adding more shrimps - i have sweet-water mentality, where it’s recommended to have even a tiny group due to social nature of the most of species. however, i’m aware it’s not similar with marine tanks, and if so, i’d have to have at least 100l (~26,5 gal) and i didn’t want to get tank of that size :ccc
a my main concerns behind volume were mostly the weight of the aquarium (as it weighs more than i do) and spacial arrangements + i just wanted to make bobo happy and well lol.
as of now, i’d be keeping these 4 fellas in total and see how they interact with each other. which other animals could i possibly introduce with time? do you think it may be okay to add another durban dancing shrimp? i found out that they need more space, but idk maybe if there were 3 in total, it wouldn’t hurt?
i’m open to your suggestions and advices as it’s still the beginning for me! i also want to know others pov and experiences, so feel free to comment!

Wanting a coral that’s different but not invasive for my first.

Not very popular, but I love how these grow. Photo taken under exceptionally white light with no filter or post editting. A cool old school sps coral.

Hi.all, this has come in on some live rock, very unsure what it is. First seen it a couple weeks back but this is the first time ive seen them come out. Also did not realise there were 2 until this video. Tia

I need help figuring out what this is. I have suspected cyano but its persistence has me questioning it. I have tried Flux Rx and it has done nothing. I suction it out and do a 3 day blackout and it will disappear for a week or two but it always comes back. I feel like I’m losing my mind. My nitrates were higher and I have worked to bring them down and I’m dosing to bring up my ph too. Any and all advice is welcome.
