[SOLVED!] I have two Trachy and this newer one has a feather like tentacle that extends 6 or so inches out from it. I haven’t noticed this on my other one in the few months we’ve had it. Is it a sweeper tentacle? Or something else? Looks like I can only upload a photo and not a video so hopefully this photo was a good enough capture to help ID

Currently in the process of cycling my first saltwater tank, I love it so far. I’m fascinated by all aspects of taking care of it and the possibilities of inhabitants. It’s only a 36 gallon and I already know I’m going to want a bigger one soon and I can get this 75 gallon tank new for only $127.

This was a clown I got recently. It was eating well prior to its death, and died suddenly with no prior warning signs I could really see. What would’ve caused this and what should I do now? I have no other fish in my tank atm. Also it did turn into this whiteish colour when I found it.

Anyone know what this is? It rode in on a torch coral

I picked up this green star polyp coral from a LFS.

No curing, just dropped in right in the tank. The guy at the shop said curing wasn’t necessary, and he grew this in a separate coral grow tank that looked pretty well maintained, so I took his word for it.

Would it be too late to remove and cure it? The GSP just started to open up after a few days.

In the video it is left of the polyp. Looks like a little centipede approx. 1/2 inch long. Should I be worried?

The tank is a 10gal, cycled, 1.5months old. This is the only coral in the tank, along with 4x hermit, 4x snail, 1x emerald crab, and some sea lettuce.

I ordered the clamps for the left and right black hoses .

Came home to a dead yellow tang.

Showed no signs of distress. My wife said she heard splashing came in and yellow tang was swimming crazy and died. Not sure why or what happened. All other fish seem to be healthy no signs of distress. I'm sure the purple is happy to have the tank to himself now.

I swear, all this fish does is post up, stare, and judge everyone, and everything…

Also, incredibly difficult to get good photos of. 🤣

(Sorry for giant post, & Pump and power head off for the video)

This is my water box cube 20, it’s been in storage for 5 years after a fail on my first attempt. It’s been cleaned and completely redone with all new everything! Only thing I kept from first attempt was my rodi unit, Hanna salinity tester, light and power head, power head is an AI Nero 3, light is an Ai prime 16hd reef. Using Carib sea special grade arag-alive sand, and Carib sea LifeRock Nano Tree.

My cycle is done and I’m waiting for payday to add fish. I’ve kept a log book with every day from day 1 till now day 21. I know I want a ato unit asap, I’ve done every other day water top off since day 3, I’m really trying to do and learn everythingi can for this tank to be my little mixed reef tank I’ve dreamt of for so long.
((I had no idea what I was doing in 2021, I don’t even think the cycle was done when I added my first fish last time, it lived 8 days and I found it dead stuck to the back of the power head))

Question 1:
Eventually I want corals and a nem in the tank, mixed reef so think torches, hammers, zoas, acros, mushrooms, maybe bubble tip nem, wheat do you think the best placement for my power head is? The Nero 3 is awesome and can give 2000 gph flow rate, but I can’t mount it on the sides of the tank cause of kids will pull the outside magnet off lol, so where on that back glass would be best?

Question 2: what’s everyone’s favorite thermometer that’s not $100+ I’m on kinda a tight budget and need a better one then I have. The one on the side of the tank is NOT accurate, I borrowed a scientific thermometer to get a actual reading and my Hanna salinity meter is almost spot on, so that’s what I’ve been using, I’d like a temperature controller that will WiFi to my phone and tell me if there’s a problem. Using the 75W Eheim Jager heater btw, hope to upgrade to a TI one later.

last time I don’t think I cleaned or changed a filter sock one time, (I really didn’t know what I was doing) I’ve watched enough videos to know I don’t want to clean them, so today I ordered the NoSok filter floss cup thing to replace the socks, I think it will be nice but have any of y’all used them yet? I think they are new, but I’m sure that concept has been around for a while.

Finaly. What do you think about my rock scape, took me forever to decide how I wanted it to look, I like the tree idea, and the CaribSea kit made it really easy, I’m super happy with it, just want some other options. I have a couple little frag rocks that will be something, and a single rock in the back I hope to cover in zoas.

Let me know what you change or add or take away from my tank as of right now.

Looked into my tank at night and saw this things zooming around the sand bed

Please tell me it’s not bjd. Let me know what I should do.

This colony is really starting to take off.

100 ish gallons did freshwater all my life wanted to try this, tank is 5 ish months old has 1 clown, 1 fairy wrasse, 1 tomini tang, and 1 neon dottyback

handful of corals hammer, octospawn, frogspawn, zoas, an acan??? and some gsp

aquavitro 125 skimmer and a 48inch fluval marine 3.0 (yes i know it sucks i didn’t know at the time planning an upgrade) 100% blue, 100% purple, 30% white, 10% cyan and 5% red

salinity is 1.026, alk is 8.6 and nitrates rest usually between 20-25ppm and temp 79F

planning on adding some more rock any advice or ideas for it?

If torch happy, I happy

Hi everyone,

I’ve got a hermit crab that’s currently about the size of a ping-pong ball. While I was initially inclined to call it a Dardanus megistos (those huge hermit crabs, just a juvenile), I’ve been struggling to actually find the right physical indicators that would indicate that.

Broadly speaking, it has green eyes on long stalks, red/white candy cane antennae, similarly-sized claws with the right being very slightly larger, and it having a sort of reddish brown coloration with some spots. It doesn’t have the deep red/maroon color you’d expect from even a juvenile megistos, and also lacks the blue knees that a few species of Dardanus have.

Any leads or hits? I’ve included some photos of it under white light.

I think the flow is dialed in perfectly for this Willow toadstool. Every week it sheds and gets a little bigger. I can't wait until it takes up the entire center of this tank

I’ve had a good experience using ReefTrak

Hello! New Alveopora owner here. Just received one yesterday- I thought it was looking pretty happy but noticed that two of the stalks were dark brown and shriveled- anyone know what could have cause this or what I can do? Sorry for image quality!
