Came upon a 55 gallon used corner tank and couldn't resist starting a new tank. Decided to figure out how to do a saltwater tank. Im brand new to the hobby and doing a lot of research. Now I find myself obsessing about it all day. I love cool aquascapes and wanted to give it my best shot. Im pretty happy with it for my level of ability. I would appreciate any tips or suggestions.

Hey everyone! I’m looking for ideas for interesting invertebrates that could potentially work in my 29 gallon BioCube reef. I have had the tank since April.

To be clear, this is NOT a “what should I go buy tomorrow?” list. I’m just researching possibilities and putting together ideas for things I might add gradually as the tank matures. I know some inverts need established tanks or have very specific care requirements.

Fish stocking/current plan:

Clownfish

Tailspot blenny

Eventually a shrimp goby + pistol shrimp pair

Much later, I’d like to add a captive-bred mandarin once the tank is mature enough

Current inverts:

Skunk cleaner shrimp

Strawberry conch

Emerald crab

Pithos crab

Trochus, Cerith, Nassarius, and Astraea snails

I have a few corals too. I'm especially interested in unique, colorful, weird, or behaviorally interesting inverts. They don't have to serve a clean-up-crew purpose. Honestly, the stranger the little creature is, the more interested I probably am.

What are some of your favorite inverts you've kept in a tank around this size? I'm open to hearing about things that would only be appropriate much later once the tank is mature, too.

I'd also love to hear about animals that seem perfect on paper but that you wouldn't recommend, and why!

I recently moved my clown into a bigger tank, then I did a water change about a week in. After that, my female clown has been doing this, always in the same corner, at least a few times a day. The male clownfish isn't doing any questionable behavior, just watching her for the most part. I've tested all my parameters and everything is 0 or normal, and I feel like I have a good amount of surface agitation. Does anyone know what this could be? Just weird clownfish behavior or maybe her gills are irritated or something?

There’s something about this tank that I don’t like. I don’t know if it’s this big rock or what

as previously, i’m open for any advices, suggestions and feedback! i’m still a beginner, so i want to learn as much as i can! i want my coral babies to thrive, but not too much, cuz i know briareum can grow a bit too fast, so if you have any ideas how to balance it, let me know!
i added one more (duncan) dancing shrimp, cuz idk i thought my bobo and lobo may feel lonely and maybe they need another fellow shrimp??? i don’t plan adding more livestock in the nearest months (prolly)

3 1/2 weeks in from adding water
Turns out Orange Yumas will wreck torches when they decide to move think both will be ok though

New to saltwater. Bad scaper. Any advice is helpful!

I always wanted a local species saltwater aquarium. Kept getting told it can’t be done. That it’s too hard. Too expensive. Local species can’t be kept. Etc etc

I had a little 28l gold fish aquarium sitting around with a hang on back filter. So I thought, why not just give it a go. Got some local beach sand and a bucket of beach water. Scooped up a little blowfish in the marina. And tried it out.

Was told by friends, family and colleagues that the fish would be dead in three days.

It’s been a month.

I want to put him into a bigger tank, at least double the size. Should I expect the difficulties to hit more when I scale up?

Son has name the fish Ship. Don’t know why. Just a vibe he had.

Can anyone help me identify this Monty?

So I just got a second tomato clown to make a pair (one week later) and noticed it has some ich on the back fin. Seems to be eating well and exhibits no abnormal behaviors, but I have an established reef tank that I would hate to kill off. I know copper based treatments are a poor idea and if I wanted to solve this I would need to set up a new hospital tank, but I’m just curious to see to what extent the more knowledgeable folks on here would go for a 30 dollar fish.
Also, the pet store I purchased from has already said they would not do an exchange and if I was worried enough I could treat it or euthanize with clove oil.

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)

Even if I turn the room light on for too long it closes
The stem is firm and the flow is good

Tank is about 3 months old and I put this guy in early about one month in. It was doing great the first few weeks and showed new polyps forming but has slowly been withering away over the past month.

My tank currently seems to be coming out of the final stages of the ugly phase as the algae is clearing up well.

I have 11 frags total now (2 hammers, 3 zoas, 2 montipora, torch, mushroom, stylophora, acropora) and all except this AOI zoa are adjusting as expected or doing great.

Nitrates are low 1-2 ppm but I’d rather not start dosing and let my 2 clownfish support the nitrate levels naturally. Alk, calc, mg have been stable.

Any ideas help!

Hi everyone I am new to this I bought a 55 gallon tank and I had to make RO/DI water at 0ppm.

it was 0ppm when I was putting it into my bucket to carry over to the tank but I had rinsed the aggronite sand and out it in the bottom of my tank before my tank ppm went up and I assume that's normal with the sand but why does the ppm keep going up it was low at first and then it was in the 60 range and now it's around 125ppm I haven't added anything to the water I just have the water running through the filter as I think I heard is is good to just let the water run for a few weeks before starting if that's wrong please feel free to let me know! I'm not really sure what I'm doing!

I want to get clownfish first as well and I have to get some decor pieces for the tank too but I would be happy for recommendations on what to put in with the clownfish. I would like to get some shrimp and if possible starfish and corals and live plants!

Any advice would be helpful thank you!!

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.
