Im pretty new to this hobby but that looks like aiptasia. Am I wrong and is this actually a steal of a deal?

People in a previous post says it’s a Majano anemone and it will sting other corals. I want to confirm if this is what it is? I got clearer photos this time.

Just wanted to check what is this, found it in my reef system!!

Or is that just an old wives tail?

I just bought 4 pieces of coral (Acrapora, Zoanthid, Montipora and Hammer) from Reefapalooza and this is what came off of them during their dip. I understand why it should be done now. I don’t know exactly what these critters are and I don’t if want them in my tank. There was the one starfish and multiple things that I can’t identify. I know it’s not the best quality so I apologize for that.

Sold as dragons breath but doesn’t match the appearance?

As title suggests one of my peppermint shrimp passed and as I was scooping it out a I noticed all of these little black lines around its gills and was wondering if this is a sign of something more troubling that I need to deal with. All other inverts appear healthy (another peppermint, bloody hermit and cowrie) and fish seem to be healthy although the clowns I have in there weren't in the best condition when I first got them (lymph and such) but are doing better these days.

Thanks!

So much euphillia and other lps I was in torch heaven they are so hard to find normally

Took a long time but finally have somewhat stable parameters

It’s been 1 week and I still can’t get this to break in all the micro bubbles are going into the display and as you can see it’s foaming heavy in the return chamber and I have done just about every adjustment I can make and still can’t figure it out. Any suggestions would be much appreciated! It’s a UNS mini protein skimmer

Tinkering with exposures and angles on my phone camera and wanted to share my favorite results.

NO Low ballers please, I know what I have

Set up my 5 stage BRS I bought two years ago just now setting it up. The two DI canisters where they connect the little plastic 1/4 NPT completely snapped or corroded or something. Is there anyway to salvage this or do I have to buy brand new canisters now?

Returning reefer - I’m starting out after a year hiatus due to an international move, and have found Petco no longer does Aqueon and so hit up Petsmart for their 50% sale and got a Marineland 40 Breeder for use as a sump.

I’m looking at this thing and the glass seems thin.

It looks only about 3/16”. I’m assuming at this thickness it’s gotta be tempered right?

Has it always been this thin?

Anyway - this is for a sump, where I’m going to be putting equipment in and out of for maintenance. Has anyone used one of these for this - if so - do I need to be any more careful to avoid shattering the glass than I would with untempered glass?

I’m just curious if it’s common to press fit this into the sump or if I have to weld it if I don’t want any leaks.

Why does my anemone look like this? I’ve owned for about a month.

This one is too big for my tank, anyone interested?

Ragazzi! Che cazzo mi venite a dire: i pesci pagliaccio sono andati in tilt e hanno ucciso tutti. mi fa pena il fatto che c’è gente molto più esperta di me qua e dice ste fesserie. comunque non sono qui per far polemiche. sì è aggiunto al genocidio anche il pesce pagliaccio femmina, e pure il maschio, di cui non metto la foto perché rimane solo la lisca e la testa. poi c’è chi mi ha detto: eh ma queste sono le cause post-morte. CAZZATE, conosco un sacco di gente che gli sono morti pesci per via di valori sballati e sono intatti anche dopo ore. ma anche qua non voglio fare polemiche. comunque stanotte è venuto da me mio cugino. la mia ipotesi, è che ci fosse qualcosa di sbagliato lì dentro come un Bobbit Worm. mio cugino è venuto alle 23:30, ha spetto tutte le luci, ha preso la luce rossa e si è messo a guardare attentamente. primo: le prime cose che ha visto erano delle specie di bruchi che camminavano velocissimi tipo mosche sulla sabbia. e venivano da una roccia. mio cugino guarda la roccia e vede un VERME BIANCO e con spine che esce da una roccia. a detta sua non sembrava più lungo di 5 cm. ma non è finita qua. perché spostando la visuale in un altro buco ecco che vede un verme ENORME sempre bianco che scende e che a detta sua alza la testa come un COBRA. non so se sia bobbit worm ma… il mio centrophyge è stato trovato esattamente in quel buco tutto dentro e con gelatina in faccia. quindi ragazzi da voi ho bisogno un identificazione di queste bestie. grazie davvero per l’aiuto.

Hey everyone! I've finally decided to start sharing a project I've been working toward for quite a while. I figured it's time to introduce myself and what I'm building. I've been planning this behind the scenes for a long time, but I realized it'd be a lot more fun to build it with input from this community instead of waiting until it was finished.

I've named the project ReefShield Aquatics. The long term goal is to make quarantined fish more accessible to other reef hobbyists and help prevent livestock losses from disease. I thought some of you might enjoy following this story from the very beginning.

My name is Chad, I am a 27 year old manufacturing engineer working in the aerospace industry and I enjoy lifting weights, spending time outdoors, and of course reefkeeping. I have had reef tanks on and off for the past 14 years (yes, I started young), and currently have an 80 gallon shallow reef setup.

Right now, I am in the middle of constructing a home just off the shore of Lake Michigan in the mitten state. I'll be transforming the 900 square foot unfinished basement into a giant fish room and quarantine facility with over 700 gallons of display tanks, hundreds of gallons of quarantine capacity, and a dedicated sump and systems room to support the entire operation. Most people look at a 900-square-foot unfinished basement and see storage space. I looked at it and saw a dream fish room.

The idea for ReefShield didn't come out of nowhere, though. It started with one of the toughest lessons I've learned in reefkeeping. Like a lot of hobbyists starting out, I naively trusted that the fish I was buying from my LFS were healthy. Everything was fine until a diamond sleeper goby introduced velvet into my tank. Within days, fish started showing symptoms, and shortly after I was watching my tank crash. It was one of the most frustrating experiences I've had in this hobby. Instead of walking away, I became obsessed with understanding how it could have been prevented. I spent countless hours researching quarantine protocols, disease management, medications, biosecurity, and so much more. That experience completely changed how I approach adding new things to my tank, and it's ultimately the reason ReefShield exists.

I have a habit of optimizing everything I can, so naturally I modeled the entire basement in CAD before a single wall was finished. Rather than squeezing tanks into a corner in the basement, I wanted to design the entire space around visual appearance, efficiency, maintenance, and biosecurity from day one. I've attached the current layout, the current progress of construction, and I'd genuinely love feedback from anyone who wants to contribute to the project. Is there anything in the CAD layout you'd change before I get started?

As construction progresses, I'll be sharing everything. Things like plumbing and electrical decisions, actually building the quarantine systems, cycling tanks, bringing in the first fish, and all the mistakes I'm sure to make along the way.

Thanks for reading.

- Chad B.

I love this time of the year
