invertebrate

Hello, I have a Fluval Evo 13.5 that has been set up since early October of last year. It has had a big algae problem since the beginning and I’ve had different inverts during this time. Currently, I have a tuxedo urchin and three electric blue hermit crabs. The urchin is pretty small but there...

Hey y'all! My tank is showing diatoms finally so I was thinking it was time to get a CUC. I would like to avoid hermits and do a snail only CUC, but not sure how many of each to get. Since I am in the beginning stages, I figured half the amount would be efficient for now, but the problem is that...

There are a few different common names for this star; most often it is called the African Red Tip / Knob Sea Star, but it is also frequently identified as Red Spine Star, Red General Star, African Sea Star and Red Spine Star. Like all the sea stars that have “linckii” in their name, Protoreaster...

Can can add a invertebrate straight to my display tank? No quarantine

At some point in the future, I would like to set up an aquarium with only invertebrates like snails, crabs, shrimp, brittle stars, and so on. (no fish or corals!) These are in my opinion, some of the most fascinating members of the aquarium hobby and reef ecosystems in general! So naturally I...

Of all the colors to get into your aquarium, red is one of the hardest. There are few corals, and not that many fish that are dominantly red, the ones that are often huge, or hard to keep, or expensive. There is however, the Red Linckia Sea Star. They range in color from a deep royal red to a...

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...

I have a 16 gallon mixed reef tank that already has a pincushion urchin, fire shrimp, coco worms, rock flowers, and a couple of snails. I also have a pistol shrimp. Unfortunately the pistol shrimp never comes out during the day and loves to grab corals and pull them into its lair at night (even...

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.

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...

Hi guys, I just noticed this in the glass of my tank. Does anyone knows what is this? Is it dangerous? It has like starfish shape.. I never seen this in my tank.

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...
