Colleagues, A quote from another topic: The globe and the pencil are very interesting. Who else has the same situation - the higher algae are not affected (and also so that Carolina eats less) and the corals are not moving? Is it the same for everyone, at least with the globes, or is this more of an exception?

I have a Tripneustes. It crawls wherever it wants, even on corals. If the coral isn't firmly attached, it will drop off. So it can't be considered a reef inhabitant. But it's been living for three years now, so I feel sorry to part with it.

Jonathon8514

Does the higher and Carolina eat a lot?

Michael826

I have such a creature: nothing bad has been noticed about it, although I have corals in place just to prevent them from falling... where the eaten Carolina was, another one appears quickly, much brighter, and it often eats not the Carolina but all the junk left on the rocks since the start, and then the Carolina appears... in general, it's a good creature...

Hedgehogs have one disadvantage - they are nocturnal. During the day, they hide from potential enemies, and at night they come out to "forage." The second disadvantage is that they tend to push through obstacles. Everything that is not secured or attached will be moved, overturned, etc. In all other respects, they are only beneficial. There are more advantages to them eating coralline. Coralline extracts calcium from the water, which is very important in an aquarium.

I don't want to go off-topic. Don't you consider this a controversial issue? Nature quickly fills in the missing niches...

Jacqueline6670

What is the controversial question? Is it about the excessively overgrown coral, which, apart from aesthetics (and that's a matter of taste), provides no benefit, or what??? I didn't understand at all about the niches. I am "FOR" hedgehogs, and not just because I like them.

I have the same one, but in red; the beast is really good, it polishes like a champ. By the way, yes, it's quite a tank.

Jennifer7159

Okay, the question that is most relevant to everyone is - who is the safest of all?

Stacey4437

They are all the same in terms of nutrition; the only difference is in the size of the needles and the amount of poorly or unanchored organisms in the aquarium.

Hedgehogs have only one drawback - they knock over everything that isn't securely placed. Otherwise, they are very useful animals, especially during the startup phase. I had a funny incident; my hedgehog (Globe) apparently decided to become a dad. He released so much sperm that the aquarium was cloudy for a day.

Melanie

They break everything... I moved stones weighing 1 kg.

Sandra7004

eats both Carolina and the thread, in general, all the junk. also poops all over the aquarium )

Volodya has a hedgehog sitting in a separate jar like a dog in a kennel, and when he needs to clean the jar, he "lets it off the leash." In my opinion, that's a very clever move.

Here the hedgehog is indicated as not being a reef safe.

Charles894

Sanddollar Judging by its shape, the sea urchin is not much of a climber. Maybe it feeds on fungi? In the descriptions, only Spanish and German variants are found. It's hard to understand.

Yolanda

Most people write that cold-water species bury themselves in the sand while still alive.
