Turbo snails eat feather dusters? That's the first I've heard of it... I have many turbos and HUNDREDS of little dusters

I'm not sure, I've been seeing all of these little tube-like things all over the tank. Maybe it's turbo snail poop?

spirorbid worms, harmless filter feeders, like these?

Nope, it looks like the tube of a little feather duster but it's all over the place. Like the snails have broken the feather duster into small pieces.

I feel kind of sad, the majority of the day my clownfish spend inside of their anemone, however, as soon as I turn off the filter, powerhead and skimmer, they are roaming around the tank and they seem to be loving it.

I almost, really want to keep my stuff turned off the whole time. It's such a pleasure to see them moving around.

Is it possible that the noises are bothering them, keeping them close to their anemone, safe?

Like ElGuappo mentioned earlier it's their natural behaviour to stay close to or in their anemone host once the hosting behaviour is established. My Maroon pair does not stray more than a foot from their BTA the majority of the time, in fact I hardly ever see the male since he spends all day behind the rock the nem is on. The female spends most of the day a few inches away defending the territory. Every once in a blue moon both of them go for a little 'walkabout' in the tank, which as you say is very cool to watch. At lights out they're both nestled snugly in the anemone.

I really doubt that any noises are bothering them. Enjoy the time you see them roam when the equipment is turned off, but I'm not sure they would do that long term. Having the equipment off too long could be hazardous to the tank's health.

Yeah, I know, I don't want to possibly affect water parameters.

Something really weird just happened. My anemone shrivelled up and constricted itself, the fish are trying to get in but they can't. It still seems healthy though.

Anyone knows what it's doing?

That looks like a Visitherm Stealth Heater which according to my LFS is the only aquarium heater to be CSA approved as fully submersible. It has the CSA logo on the box and the box says "Fully Submersible". It's all plastic and does not have an "on" light, I really like mine. My tank is always 78*. Anyone use this heater?

It is that heater and it seems to work pretty well. The nem is opening up a bit and it looks a bit better. Maybe it just got cranky?

They'll do that from time to time, mostly after they've digested something they've been fed. It's kind of their way of regulating their internal chemistry and it may expel some waste when it does that. As long as it doesn't stay that way for more than a few hours, nothing to be alarmed about.
