Maybe a silly question but can you keep a Tuxedo Urchin (Mespilia globulus) in a tank with macroalgea? And could you switch it between tanks?

I’m wanting two aquariums.

One aquarium will have more verity of macroalgea and the over being more invasive and I’m thinking maybe I could switch it between the two tanks so it can eat them without outright destroying them?

For the first tank its macroalgea will be red bamboo macroalgae, Cryptonemia Crenulata, dead man's fingers macroalgae, branching hex macroalgae and orange galaxy macroalgae.

The invasive reef will just have blue octodes and caulerpa taxifolia.

But is my idea silly/dangerous?

Looking for help IDing this coral.

Each polyp has a large stony tube shaped base. From what I can tell it is for sure a LPS coral. The tips look exactly like goniopora, however skeleton does not make sense for this. From what I can tell all extension is stony with small fleshy tips.

Shriveled Hammer

I got a green hammer about a month ago and it was doing great for the first 2 weeks. It started shriveling 2 weeks ago and now it’s seemed to shrivel up completely. I’ve done water changes for the past 5 days and i’m not sure why it’s still shriveled. please help!

Is there a less flighty version of the yasha goby? The pistol shrimp I have in mind is a candy cane pistol shrimp

Thoughts on my coral choices for my 20 gallon reef tank and any suggestions for possibly more?

Thoughts on my coral choices for my 20 gallon reef tank and any suggestions for possibly more?

The tank’s dimensions are 33cm wide, 72cm long and 40cm tall.

The corals I’m thinking a Kenya tree, Duncan, blue green sympodium and mushroom corals.

It’ll also have macro algae like the red bamboo macroalgae, Red Grape macroalgae, Cryptonemia Crenulata, dead man's fingers macroalgae, branching hex macroalgae and orange galaxy macroalgae.

I like diversity and movement, but I’m also kinda lazy so stuff that likes dirty water and okay for beginners.

And zoanthids

I need some fish, snail and invert stocking suggestions for a 15 gallon invasive/pest reef tank

The tank in question is 29cm wide, 58cm long and 42cm tall.

Originally I just wanted one treed tank, but I really wanted pulsing Xenia and blue octodes, but they’re highly invasive so I thought why not have an invasive reef?

For macroalgae I have blue octodes and caulerpa taxifolia, for corals I’m thinking Kenya tree, pulsing Xenia, green star polyps and mushrooms.

And for inverts I was thinking a Pom Pom crab.

I like inverts but also like colourful gorgeous fish!

Any suggestions guys? I’d like this set up to be low maintenance as it’ll be a pest/invasive tank as the macroalgea and corals will be battling it out.
