invert care

I recently added a porcelain crab to my nano, and I read that some species host in nems and some don’t. Can anyone ID him and tell me if he’s one that would prefer a nem in the future? I’m worried that if he is an anemone crab then he and my clowns will fight over it. I also know he’s a filter...

Hi there, Attached are some photos of my rock flower anemones. My orange one was a previous resident and was happy and didn't move from his spot. I added the green one on Saturday, close to but not touching the orange one (to make a rock flower garden). Since then, they have both moved closer...

I have a new 25 gallon to wich im transferring two clownfish, tailspot blenny and blood shrimp. I don’t want to add any more fish and instead want to focus on inverts, I love them, crabs, sea stars, urchins, you name it. What is a good list of good inverts I can add that aren’t super tiny...

First time it came outThe night of the same day The last 1min Video was just shot. I never expected a feather starfish could have an individual part just like a serpent, yet it’s extremely sensitive to light. Seems doing great Since I introduced it to my tank, this feather star haven’t lost...

Hi there - I’ve had this snail for about 2 weeks and just noticed this scab/lesion looking thing on his back (not the shell). Any idea what this is or if it’s a sign of something bad for my other fish?

Hello all, I am new to reefing. I introduced a couple blue legged hermit crabs, bumblebee snails, Astrea snails, a peppermint shrimp, and a clownfish. My peppermint shrimp is super curious and friendly. I see him often. The Astrea snails I see most every day too. But, I hardly ever see my...

There is such a wide variety of both hermit crabs and snails, are some more or less compatible with eachother than others? Would a smaller hermit crab like a scarlet still kill a snail like a large trochus who's shell wouldn't even be suitable for such a crab? I would like to hear peoples'...

Its been a while since I've had a saltwater aquarium, but I'm finally ready to jump back in. My previous tank was successful for the most part but I now know that I should do a few things differently. Mainly, not placing it by a window!!! As well as taking things slower and not messing with the...

Wasn't going to post this for fear of things going badly, but decided to post anyway because it could help someone else have success in the future. I acquired 2 Pacific brown octopus 1 month ago on Sept 8th 2023. Same day shipping. One died the next day, the other survived ("Nugward"). I...

Hello everyone, I initially started up my 15g nano reef tank in December 2022 so I could get saltwater inverts, as I was interested in them. However, I have had crustaceans dying one by one, with about 2+ weeks to one month intervals between deaths. I have tried everything to figure out what’s...

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...

TLDR: I want to add a sexy shrimp or two. Alright everyone my Small but Mighty tank is up and running, has been showing stable parameters and good growth so I would love to add my first invert. A sexy shrimp. Currently we have no inverts or fish so it will be the first addition to our tank...

Just made a big mistake hopefully this serves as a caution for others keeping sexy shrimps with Yellow Watchman Goby. I have had an existing colony of six sexy shrimps with my Yellow Watchman Goby & Pistol Shrimp pair. I decided to add 5 more sexy shrimps hence after acclimating I was adding...

My name is Ghost. The video above features one clip or photo from all 365 days I have been imprisoned. Watch me grow! I was once a small crustacean larva living in the Yucatán Caribbean Sea. I found a tiny beautiful shell, but the next thing I know I was out of the sea. Looking around, I...

Hey all, so for over the past year or so I’ve tried to keep cleaner and fire shrimp in my reef tank, but for some reason I can’t keep them alive for any longer than a few months. It always comes to me checking out the tank one morning, and seeing what looks like a molted exoskeleton and the...

I’ve had a Staghorn hermit for about a week now. He is clearly picking at/eating from the substrate of the tank. The hydroid looks healthy and I can see extension so it seems to be taking in Phyto and whatever else from the water column. It doesn’t move very far though and I’m trying to figure...

Hi everyone! I went to my LFS yesterday to pick up some more inverts for my aquarium, specifically sand sifting inverts since my sand bed is thickish and gets dirty. I picked up 3 nassarius vibex snails and a sea cucumber. The sea cucumber I picked up was a pink spiny sea cucumber. I know...
