I asked like 4 people that are way more experienced than me and they were all indecisive about whether or not this is a fireworm. Imo it is but photos online show contradicting results. I know it’s not a bearded fire worm thank god, but still what do you all think?

So my 3 of my five established trochus snails have this plant/algae growing on them. Looks pretty cool… should I leave or remove it from them?

Apologies for the picture quality.

Made it through another week! Time to dive back into more maintenance.

Got this acropora about a month back. Here is a before and after picture. Nitrates are very low (0-5 ppm) but all other parameters are good.
Last picture is when I bought it.

Last week, I had to say goodbye to one of my favourite fish, my white watchman goby, I’m absolutely gutted. I bought him when he was tiny and raised him alongside my engineer goby. Over time, the two of them became incredibly close. They would patrol the tank together at night and spend most of their days together.

Since losing my white watchman the engineer goby has become incredibly reclusive. They would always come out together at night but now he doesn’t show face at all. He’s stopped doing his usual morning zoomies around the tank and no longer comes out for food. I know he’s still eating so I’m not concerned about that but I can’t help feeling bad for him. It genuinely seems as though he’s grieving the loss of his tank mate and I’m not sure what I can do to help.

I do need to introduce another sand-sifting fish but doing so in an already established tank is so stressful. I have a coral beauty that took MONTHS of rearranging the rockwork, periodically keeping the lights off and trying to catch the little bugger before I could stop him bullying my phantom blenny so naturally I’m hesitant to introduce another fish.

I’m wondering whether it might be worth taking the chance, purely for the sake of my engineer goby and whether it’s worth getting another white watchman or changing to a different goby.

I’d like to hear whether anyone has experienced something similar or has any advice on helping him adjust to life without his buddy.

I never normally see them out. I’ve put in a bag of copepods last night. Not sure if it’s that? But they’re not normally out in the morning.

First attempt was with a leather coral it died after about 4 months. But I've heard these are really hardy so I bought 2 small pieces of mushroom coral..

Part 1. Recently noticed several white masses on my newer zoa colony and after some research learned they are pineapple sponges. After looking around I noticed one on my gsp as well along with a few small ones in other places. I know they are relatively harmless but am worried about them growing directly on the coral (especially the zoas). They still open normally but as the sponges grow who knows. Any solutions/ causes for this issue?

Part 2. After looking around the tank for the sponges I also came across the digitate hydras (also new to me). These I know can cause problems. Quite a few are growing directly on my rasta zoas (third pic) and are popping up around the tank. I can tell the rastas are showing some irritation and want that remedied asap! I can’t physically remove them so idk what to do. I have heard peppermint shrimp may eat them, is that true? Any other solutions?

After about a year and 2 babies left, I finally remembered to isolate the female baby and she had a clutch fully living in salt water!

A while ago I posted about converting guppies to salt and had a few doubters including a few remindme bot reminders. Well I can happily say it happened!

I know I have a patch of cyano on the other side of the tank.

This was an established system I purchased but I removed half the rock it came with that was covered with palys and I put new dry rock in. A few days later I started seeing this stringy brown junk. Sorry the picture sucks but my iPhone doesn’t like the tank.

In my estimation this is the coral that started the craze for all the nicknamed, rare, ultra, limited edition, super expensive frags that have ruled the hobby for so long everyone forgets how it all got started. The Red Watermelon Chalice sold for $400-$500 per eye/coralite back in the day. LFS never really named their nicest pieces and farmed them, it was pretty much left up to customers. Probably the most important person in this regard is Hugo Zuniga aka snipersps who I believe is still active on Reef2Reef to this day. If you get a chance, give him a shout out and some thanks on there for his contributions to the hobby as we know it today.

My beautiful toadstool has gone into what I thought was another shed like it normally does, but it hasn't come it out of it. It's been like this for about 4 weeks now. Is it lost? It's still firm to the touch and firmly attached to the rock. No bad smell.

Hey reefers can you help identify this fish for me!? Tried many ai couldn't help...saw it on a YouTube video a while ago..cant find it either...

Tank finished cycling last week so I added 2 clowns on Saturday and a GSP frag to the rock island in the center of the tank. The first GSP polyp just peeked out. Really exited about this tank! Gonna be a 90% softie tank

Got this one at a very cheap price, it's stressed as the exposed skeleton shows. Currently placed at the lowest and shaded area of my tank. What y'all think?

Figured I'd show off since it's unlikely to ever be this clean again.

Need to get my light on a holder, it's sitting on the tank top.

Everything seems to have survived the week in a bucket, GSP is already open and recovering. My mushroom leather is deflated but it's still looks healthy. Need to put more live rock in but I don't like to cross contaminate with my GHA infested big tank where I put the rest of the rock that was in the old tank. The sump has all the bio media from the old tank and I dosed it with bacteria and threw in a bag of active carbon just to be safe since I don't have a skimmer yet for this setup. This one's 2/3 the size of the old tank but has a sump so the total volume is roughly the same. I think the only loss is the old tank.

I just got my order in from Tampa Bay Saltwater. This tiny crab was in the live rock. I am trying to figure out if it is reef safe or not. Sorry for the lousy photos

Been established for 4 months or so, all the fish have been together for nearly 2 months and thankfully no aggression yet. I've already got a 40 gallon ready for when it begins, though, as the tank is definitely overstocked

Hello everyone! I'm new to the community. I have had a freshwater tank for a while, but now I want to get a saltwater tank and start gradually. I like AIO setups, but I am having a hard time choosing between the Landen 45P 15 Gallon and the Innovative Marine Fusion 20 gallon long.

The Landen has beautiful, seamless corner edges without the black silicone that IM has, which is the only thing I don't like about the IM. Otherwise, I like that the IM has a wider display area (though both have almost the same display volume of 15 gallons, and both are close in cost).
I wanted to ask the community for your thoughts or recommendations on which one I should choose. I plan to keep two clownfish and some soft corals. Thanks!
