I wanted to do a water change

[Daddio64]

I'm afraid I'll harm this ****** there's no immediate danger in the tank. Nitrates as always a little high. But no one minds. I've attached a couple pics. Any thoughts folks?

whats the problem?

its lockline so pull it off the return and do your water change no big deal.

I believe they can handle a good few hours out of water—low tides expose them naturally, and people often remove them briefly to detach them by hanging them upside down on the rock so they let go. Open to correction if anyone knows otherwise

Do your water change (FWIW water changes are the best way to reduce ALL the detrimental DOC in a system). Ignore it, it'll be fine (if it was in my tank I'd do it to try to get it to move off the return line.

Casual observations have reported that water changes may trigger anemones to split in aquariums. It may double or triple the chances that a nem will block the overflow in this tank?

It's fine carry on as usual. I have nems stuck all over on the sides of my lagoon and they are often out of the water when I do a water change. My water change only takes a few minutes so keep that in mind.

You look wrong in the direction of RBTA’s they split, fart in their direction boom split! But Sherman’s, black widows, CSB, or Chicago SB’s seem to be less prone to it. Had a Sherman that would rather die than split. It was a ich break out some years ago, and I decided to try dosing things in the DT only to have it wreck my corals after the whole dosing ordeal. Sadly didn’t make it. But RBTA all made it! And splitting all over the place. From 7 to start, I ended up with double that. Gave them all to a buddy of mine who ended up having the whole tank taken over. He ended up selling them haha.

Not only can you do a water change - you should do a water change, if only to get that bugger off of the return line.

Fortunately if it's on a plastic surface it tends to be easy to detach and relocate. My own feelings on BTAs aside, it's in a problematic area there and it will eventually cause a problem. But it looks like there's a LOT of dead space between where it is and the top of your rockwork - is it perhaps light-starved? You may want to look in to finding a way to give it a permanent home with better light than it otherwise has access to.

Yep, better than it letting go in its own and being flung into random orbit by the flow, stinging everything in its path.

I agree that I would move him to the off the return line, then do the water change as normal.

In Ketchikan they have huge tidal changes. 10-15' range. When I was there the docks go up and down with the tides with holes between the posts so they can rise and fall.

At low tide I was on the dock, getting onto a seaplane, and there were anemones 8-10' overhead completely out of the water, exposed till the tide came back in. So, yeah, they can handle a while out of water and do it in the wild frequently. Sure, likely a different species in cold water but I think it is relevant.

Don't have a good shot of the anemone on the rafters but here are a couple of shots of the tidal area near the dock. Sea cucumbers, crabs, anemones all right there. An abundance of wildlife. For reference, those red and white cukes were about 10" long and can get up to 20".
