The alkalinity in my tank seems to be dropping steadily (about .1 dKH/day) independent of the other parameters. All parameters are tested daily because my humans are new to reefing and want to understand how everything works together. The other parameters remain relatively steady at: Temp...

Hello reefers, My name is Ghost and I am a tiny marine hermit crab. One day in September I was just minding my own business, sifting Caribbean sand, when some loud divers thought my beautiful shell was empty and took it. Upon returning home and discovering my existence, they promptly set up a...

Hey all! I posted awhile back about my beautiful peacock not smashing hermit crabs or turbo snails in tank. After a few suggestions I bought a crayfish to see if it would be big enough for it to smash and eat but it didn't seem to workout and almost seemed like mantis was losing the battle so I...

I saw this orange spiny lobster on Diver's Den, does anyone have any additional information on these? How would it do in my 65 gallon tank with soft corals. Any information such as food and if they knock things over would be helpful.

So I might be missing something but I thought copper was bad for inverts. I have just bought a new tub of vitalis marine pellets and noticed one of the ingredients listed is copper sulphate. Is this not going to be bad if one of my shrimps tries to eat it. I'm sure it's safe else they wouldn't...

I’m looking into sea cucumbers, the pink spiney and black and pink cucumbers. The issue is some websites say their care level is easy and others say expert only, so which is true? Anyone have either variety and have any insight?

Purchased as a “fire” urchin. Not sure what it is any help is greatly appreciated.

Do you guys think using Instant Ocean Sea Salt (Purple Bag) is ok to use for a yellow coral banded shrimp? Does it have enough iodine and other trace elements for it. I also have 2, 5 gallon buckets of Instant Ocean Reef Salts. I'm going to guess this one is better, but was just wondering if...

My all time favorite is always Conch, Conch, and Conch. Such a fun, interesting little creature. Those long eyes that react to your action. A powerful leg that moves fast. A cute elephant nose that goes didadidadoo. A heavy body that can't climb glass. A long lived peaceful creature...

Hey everyone, so I’ve just started my reef tank up, it’s a 75L, 20 Gallon AIO reef sea max nano! I’m super proud of it, but I’ve got a couple questions regarding the addition of a CUC/livestock. im planning on getting 2 clowns and a nem down the track, and eventually adding some SPS corals. I’m...

Hi, I have a Fluval evo 13.5 gallon and am thinking of getting a strawberry conch once my aquarium is established, is the Fluval evo an ok sized tank for them?

My heater fell onto my big beautiful BTA last night and cooked half of it. I fragged it to try to save the half with less damage. Both sides are in a quarantine box and both are alive and the foot is sticking. The “bad” half looks really bad but does have a few live tentacles. The “good” half...

Hey everyone! So I’ve started a tank for 2021 and I thought. I was settled on livestock for the tank but I’ve fallen down a rabbit hole. I need some help! What are some unique livestock that I could potentially add to this tank? It is going to house coral so they would need to be reef safe. I’m...

There are plenty of threads asking for suggestions on what fish or inverts to get to control unwanted algae, but for those of us (like me) that want to keep attractive (and sometimes rare or expensive) macro algae in their DT, what fish and inverts have you found that are the safest to keep in...

I was just taking a look around the tank this morning and spotted what I think might be a stomanella snail? Was hoping that the group could confirm. Also, I have never, ever, seen a snail blow this smoke-like substance or whatever into my tank, but it's making me nervous. Any guidance is...

Hi, I have a 75 Gallon Long Tank with 2 Ocellaris Clownfish, a Starry Blenny, a Chalk Bass, 3 Nassarius Snails, and a Blue Hermit. My sandbed depth is not consistent but the depth is 1-5 inches, on average its about 3 inches. My reef tank currently is very peaceful the clownfish do not pay any...

Just got my first clam. I tried to be wise and started testing for magnesium in addition to all other important parameters like calcium, phosphates and alkalinity. Levels are ideal. Placed clam at bottom of Fluval 32.5 marine, medium flow. Day one open but nervous. Question or best tips/tricks...

The other day I noticed that my tuxedo urchin had climbed to the top of a rock, and started spewing powdery stuff from its top. It continued to pour out for 20 min or so, seemed never ending (the fish loved it! A mid-day snack). I've heard of clams doing this, but have never seen anything like...

Hi, I was doing maintenance in my tank and i noticed this little fellow lurking under a rock. It probably came with my live rock considering that I haven't introduced any corals yet. Should I be worried about it? Thanks!

Yeah so what the title says.

My red tuxedo urchin died today and I was hoping to get some ideas as to why. I have had him for two weeks and he was doing good traveling the tank no spine loss. This evening I found his remains. He hadn't shown any signs of sickness no spine loss and was moving around last night. I've not been...

Hi everyone, hope you’re all doing well. I have a question if been meaning to ask for a while, I’ve been wondering how you guys may offset this issue. How do you keep your reef clean if you have for example a puffer fish that loves eating your clean up crew? Is there a way you can maintain a...

I've heard that some people go as far as to supplement iodine in their tanks to help their xenia flourish. I haven't been able to verify this theory (and believe me I've tried), but that seems to imply that xenia is a bio-accumulator of iodine. And if thats true then... Well, it probably...
