Difficult and Special Care Invertebrate List

[ThisIsTheWay]

I'm not expert, and I know this thread is kinda old and most likely has some outdated information, but there are some animals on this list I don't understand the reason they are placed there:

Aren't devils hand corals are photosynthetic?
Also what about pink/purple leather corals?

Aren't these just feather duster worms? Do they also have poor survival rates?

Bubble tips are a notable exception.

Would having a refugium/sump to keep asterina stars mostly eliminate the difficulty of providing these shrimp with sustainable food?

Yes, I believe devils hand corals are photosynthetic (this thread is old enough maybe it's referring to something else that we've renamed since then?)
Corals like the koji wada pink nepthea are photosynthetic, however there are some really vibrant pink/purple leather type corals that are NPS so you'll want to do your research. If the colors are uber vibrant then it's more likely NPS.

Coco worms and larger feather dusters are not the same. I believe coco worms have a calcified/hard tube and have white and red fans. Feather dusters typically have brown/tan fans and do not have a hard tube. Both of these would be different from the smaller feather dusters.

I think we have come a long way with anemones. Bubble-tips are definitely a notable exception, though there has also been success with carpet anemones.

My understanding of harlequin shrimp is that you need a system volume of at least a few hundred gallons in order to sustain an asterina starfish population large enough to keep up with their voacious appetite. If you can't keep up, then you either need to trade your shrimp or buy it something like chocolate chip starfish to keep it fed.

I’ve had a couple hitch hike in on coral, however they’ve only been porites.
I’ve looked into if they can and it seems like they are able to hitchhike and live on other animals, including Giant Clams (Tridacna species). But it seems specific species prefer different host species.

I have a couple attached to a turbo snail. They're not burrowing, they're just attached to the outside. Really small though, don't know variety.

Does anyone have expirience with the lunulata species of blue ringed octopus? I feel that if you overengineered a tank to prevent escape, as well as used proper safety protocols that they would be an incredible species to keep. But I also know that a 5cm octopus with a 5mm beak is pretty darn difficult to contain. You would need to keep your (and others) hands out of the tank.

IMO why keep a species you can’t interact with though, I keep octos hoping they’ll want to interact with my hands and yeah blue rings are tiny! You’d probably have to cover all opening with netting or something it can’t get through. I’m currently hoping to get a bimac which is a cold water species

I might just try to travel somewhere I can do photography of them in the wild. I honestly just want some higj quality photos that I have actually taken.
