The Curly-Que Pistol Shrimp is one of the coolest creatures in the ocean! This tiny shrimp has a unique weapon that allows it to stun prey and defend itself: a specialized claw that snaps shut with a loud popping sound. The snap is so powerful that it creates a shockwave and a cavitation...

- hey do you have aiptasia? I'm hungry. Yes I would like to buy a shrimp to attempt killing aiptasia. Its a hit and miss, yes, I read the disclaimer. I'm in south carolina upstate.

UPDATE: Every response I receive confirming the balls are poop gets to play a part of the mounting evidence that I just spent multiple hours of my life staring at, photographing, and squishing urchin feces (multiple times) with my bare hands. Then I posted about it online for all to see...

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...

I bought my first ever coral about 4 months ago, a small 2 head Torch and a fungia plate coral, I dipped them both and got a small flatworm off the torch luckily. A few days into owning the torch and watching it get used to the water and extend, I noticed a little section of bristly exoskeleton...

We all like to treat our Coral with dip and maybe some of us don't do it or never have at all. I would like to know, what is the coolest hitchhiker that has made their way into your tank? Through buying Coral, live rock or live sand or anything. It would be interesting to find out if anyone has...

Hypothetically if you were Australian and you were struggling for months to find a distributor in your country to purchase a specific Nudibranch you have researched in depth, and it is illegal to import pretty much all marine animals in Australia without a license. And you didn't want a license...

If you could have one snail species in your aquarium, what would it be? Okok, well, perhaps you can include honourable mentions in order of utilitarian role. Really though, I’m interested in your desert island one and only choice. One snail to rule over your aquarium reef.

Hey community! First post here, looking to document my latest venture into exotic animal care. I had seen a post on another social site weeks ago with an Upside Down Jellyfish and never thought about housing them as I am aware Jellyfish are generally very sensitive and hard to care for. This...

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...

Hey, folks! This is my first time posting, so I hope I'm in the appropriate space for help with ID'ing. This morning, as I was inspecting my tank I noticed a sort of "ant trap" in my fine sand. I tried to do relevant Google searches but couldn't find any info. I have noticed no feelers or...

Hello, Today I was cleaning my tank and found a Trochus snail I that I hadn't seen for awhile and assumed he had been eaten. I didn't pay much attention after that until I was looking in tonight and noticed the snail is upside down in its shell (It moves on its shell instead of the substrate)...

I have a tiger cowrie (his name is Howard) and was wondering if he could eat a blue photosynthetic plating sponge. I read they eat sponges, but the plating sponges contain the hard glassy material ( forgot what it was called.) Could it work?
