Hello everyone, New to R2R, have been in the aquarium hobby for around 6 years - started my first SALTWATER tank about 6 weeks ago. I've had brackish and freshwater tanks, but they weren't scratching the itch for me. I've started with a 15 gal cube, and yesterday I was finally able to...

This just showed up in our tank one day. It pops out from one of our rocks and we aren’t sure what it is!

does anyone have an ID on any of these? Asked a few weeks ago and the only answer I got was that maybe the one with the red mouth is a gorilla nipple, not sure tho

I can NOT get phospates above 0.01. I like to do a water change at 20 for the nitrates, but would it be ok to leave for a few days to see if phosphates go up any further? I think there's enough live food and algae in the tank for the crabs and fish to eat, so I could hold off on feeding for a...

Hello everyone! I hope you all are doing well. I am a college student currently but keep two tiny aquariums that I have recently learned are not nano but pico/femto tanks. Here are some photos: I might edit to add some more later. Currently, I have 6 snails under my care: - Peter...

Hi all, I have kept freshwater planted aquariums but am new to reef tanks. Looking into purchasing a bundle and wanted to see if you all think it is worth the price. I am having buyers remorse before even buying it, but to me it is a heck of a good deal. I have to drive 4.5 hours to pick it up...

Good evening all, I am planning a new tank build and would like a tank with built in electrical storage. I'm leaning towards a peninsula. Does anyone have any suggestions?

I am Nick, from The Netherlands! I have always loved aqua life. My parents always had tanks, mostly tropical fresh water fish. And not the best knowledge, but as a kid I simply loved it! I loved to fish and be next to water. Loved catching salamanders and other aqua life. I have a bit of...

Hi all, I'm getting into saltwater, and I plan to let my tank get cycled and ready over the next 1.5-2 months (I'm going away in early January for a bit). I have a wavemaker on order and I have extra heaters and stuff to mix saltwater appropriately. But I'm curious, do I really need that for...

If you could help me ID these 2 frags I got, also have if anyone has any names on the zoas in the background that would help too thanks!

Hi everyone, I'm new to the salt water world but had spent my whole life around the fresh water world. Started up my first tank a few months ago with some help from posts from here while lurking with out an account. My Tank is going through a fallow process because I noticed velvet on my...

Hi fellow reefers, I have setup my tank last May so it has been running already for some months now. As you can see, I have added a few corals to it, a clean up crew and some fish. I am a bit struggling where to go next and in what time frame. So far, I have been focusing on soft corals...

Hi, I’m new here but i’m not new to the hobby. Some facts about me: I live in Sweden Had my first freshwater tank at 9yrs old. Malawi, Tanganyika and planted tanks My first 40L reef in 2008 (i think, time goes) Have had a couple of reef tanks, dunno how many Current tank: 500L (sump included)...

Hey guys! For sale is a brand new in box Synergy Shadow overflow, I just don't need it. The only very minor issue is that I had this stored in my garage, I left the garage door open one day, and a little bit of rain got on the box. So the box got just a little discolored, but the box is still...

Hey, new to the hobby here, tanks about 3 months old, I have a pair of clowns, the female has been pretty aggressive with the male, nipping his fins and such so I separated him in a little isolation box so he could relax for a few days, as I do not have a separate tank, but now the spots I...

Anyone able to ID these? First is a fleshy like lump with a red mouth like feature attached to my live rock, idk if it’s always been there but as some of my sea squirts fell off from pesky crabs is when I’ve noticed it. Bellow the bubble tip nem surrounded by the red. I’m unsure about this...

Hello! Bear with me. I am new to saltwater aquariums and testing, any help is appreciated. I’m testing for Alkalinity using the Hanna tester. I followed the directions and got 6.4 and 6.0. These were back to back tests. I then used a Salifert calcium test and got 400ppm. I trust this one more...

Hi all! I've been given two small corals for my tank when purchasing my Blenny yesterday, and I was wondering if anyone can help with first of all what they are, and second of all what is happening with the tree coral? It seems to just be folded over.. I am super new to this and these are the...

Of course im new to the hobby, my tanks is 4 months old. I’m running a 80 Gal redsea G2, with two reef led 90s, reef mat, skimmer and Red Sea reef spec carbon. I religiously do a 10% water change weekly and all my numbers have been steady. I think I understand the ugly phase but I don’t know how...

Impulsively went to my LFS and immediately knew I needed to start my very own reef tank. I’ve had a betta before, but that was nothing compared to this. Currently I’m a month and a half in with no issues once so ever. I wanted to do something with puffer fish, eels, and sea horses but some...

I know every tank is different and I've watched tons of the BRS videos on starting new tanks / ugly stages / etc. But I'm trying to be mentally prepared for the next "Shoe to drop" with this tank. We're a little more than 2 months in on our first 90 gal, and seem to be getting to the end of...

Hey everyone! This november will mark my 1 year in the world of saltwater! I feel as though I have a good grasp of it all, and now I'm trying to meet more people in the hobby/learn how to navigate this website! (Super cool although overwhelming). Attached are some of my favorite photos of my...

New to me but hopefully not new to others. Help in the ID of these two critters? Never noticed them until this week. Long striped strings/tentacles from the rock in multiple spots. Little guy keeps slowly coming up then shoots back down anytime I get close except for if I stay for a while.

Main tank is 2 months old (live rock start). Ugly stage is fully present and brown haze is settled in and made itself right at home. Awesome, love it, so fun. But, picked up some more fish from @Biota_Marine , a Link's & a Court Jester Goby and a Royal Gramma. I have them in a 24 gal QT...
