    I was fortunate to avoid a tank crash when one of my anemones crawled into a power head and decided to shred himself to pieces. Of course this happens the day I leave for vacation and only have time and enough water to do a 15 gallon water change. I think running a lot ROX .8 carbon saved my tank from a crash.

    Side note, I have one anemone now and it is becoming a royal pain as it likes to change places in the tank every week or two and sting any coral that I decided to glue down. It doesn't help that the anemone is the size of a beach ball. I have resorted to moving live rock around to see I can contain its location to some extent.

    You said you found it in your sump in a dozen pieces? Was it disintegration or was it mechanically ripped apart? Merely finding it in your overflow, and it taking a rid down your plumbing shouldn't have resulted in it getting shredded - unless it met a pump somehow.

    I've written before about BTA's moving, here's a copy/paste along with a few extra additions:


    Water quality, light, food, flow, and foot - the five conditions that must be satisfactorily met for all anemones.

    Water quality: In the ocean, if local currents drastically change after storms, rivers dump crap into the ocean etc, the nem may want to move to conditions which better suit its liking. In our tanks, however, there are no other areas which have better water - but the anemone doesn't know that. This is my #1 pick for why anemones move without apparent reason. It may even be something in your water which you do not test for - or it may be BECAUSE you just did a water change and didn't match tank water close enough. The anemone is searching for something it just can not find inside a glass box, hence the so called "anemone's just sometimes walk around for no reason". We can't see the reason - so we assume there isn't one. Further to the "water quality" section should be allelopathy (chemical warfare). It's been known to happen from other anemones, or from more aggressive corals as well.

    Light: Lighting in the ocean is quite strong. Far more than our little electrical lights we use. Even on a cloudy day the par is very high - ever had a sunburn on a cloudy day? When you introduce a BTA, you may have a spot picked out that you really want it to go, but it may decide it is too bright or too dim and promptly move. As it gets light-acclimated to your tank, it may move to a spot that is "just right" for its health in the long term. This acclimating and moving to a new home may also cause confusion to BTA's "moving a lot".

    Food: Yikes! There is a lot of misconceptions about the "proper" diet for anemones. I did a write-up a while back about the topic: http://www.reefcentral.com/forums/sh....php?t=1835320 A basic summary of that thread is.....assuming a healthy nem, food is not entirely necessary. If you would like to feed, feed small (pencil eraser max) meaty, raw, SW-found foods. Unhealthy nems need more food to gain energy and should be fed more. Feeding leads to faster growth. Feeding can also in some cases overcome less-than-ideal lighting because the food is supplementing the light source. More in-depth information can be found at that link. (I think the link might be broken...) Also, in an ultra low nutrient system, you may need to actually feed the anemone more, and they may need some of the "bad nutrients" we are working hard to remove - everything in balance.

    Flow: You need to determine the flow requirements of the species of nem you want, and make it match in order to decrease the likelihood of movement. BTA's will like moderate flow, but not too high or too low. Either of those may cause it to move around. Some can be very picky. I know someone who's Haddoni moved across the sandbed after he cleaned a powerhead and he thought replaced it in the exact same spot (Todd). Apparently it wasn't quite exact. Haddoni's like low flow - if their oral disk is being moved by the current, it's too much and will cause it to move.

    Foot: This is my #2 reason why BTA's apparently move without known cause. The foot of most anemones also requires special concern. Some anemones like to bury in the sand, some at the sand/rock interface, and some directly onto rocks. BTA's like to have their foot in a deep crevice, hole, or cave. Basically, it's a safe zone for them to hide in if they need to retract. It's also a way for them to regulate the amount of sun it gets. These deep holes are key to keeping a BTA happy with it's current spot. They like their foot shaded, and head out in the sun.

    Last edit: mechanical problems such as stinging corals can irritate an anemone enough that it would move.

    I have a 180gal tank with about 50 Anemonies. I used to run the "mixed reef", but after years of expensive coral loss, mostly due to roaming Anemonies. I decided to do an Anemonie tank only. This tank has been running for well over 15 years, and have not lost a Nem since taking these following precautions. All powerhead intakes have to be covered with some sponge or filter pad option, but be aware these act as mechanical filters and you need to keep them cleaned. The overflows, I covered the slots, and down a few inches, with the same mesh material that is used for our screen tops, and then covered the top of the overflow. Again, you have to be aware of junk clogging this screen, so make sure to keep that clean also.

    My tank has every combination of Anemonie I can find, I have Bubble Tips, Sebae's, Long tentacles, Haddonis Carpets, Heteractus, Mini Carpets, Rock Nems, and of course, Aptasia. They all seem to get along, I have never had an issue amongst any combination of these Nems sitting right next to each other. As mentioned above, different types of Nems like different conditions, both lighting and water flow, and to a smaller extent, food availability. Speaking of food, as mentioned above, a healthy Anemonie does not need to be fed, I have not purposely fed any of my Nems in over 15 years, of course, some of them do get food when I feed my fish. My Haddonis have actually positioned themselves downstream of where I feed in the tank, so they are getting maybe a few small bits every day. Now, when I put a new Anemonie in the tank, I do feed for a few weeks, then ween them off the direct food, but make sure the Nems tentacles are a bit sticky before you try to feed. There is nothing wrong with feeding your Nems, assuming they actually take the food, but a well fed Carpet or Sebae will outgrow your tank in no time, I prefer to keep them for years!

    Moving Anemonies, again, usually due to water flow, water quality, and/or, lighting. However, over many years of documenting my Haddoni Carpets moving, I finally realized 2 of them would move on an annual basis, same time every year, they always moved to the west, and would sit at the west end of the tank for a few weeks, then they would move right back to where they came from. Within a week of them returning to their original spot, they would spawn! This has now been going on, since I realized this, for 10years or more.

    good luck with Anemonies, i personally love them, maybe my favorite tank

    Thanks all. I had filter pad around the power heads. There was no Trace of it in the display. So I'm convinced that that it was ripped to pieces going through the overflow grate. I have 3-5x turn over in my 75ga. I didn't think the flow was all that strong It had it's foot anchored good and deep in a crevice in the brs reef saver rock the evening before.

    I think the power head flow convinced the nem to move. It's flow is deferent at night from day.

    Those of you who covered your overflow grate, could you please provide a picture. I'm not certain how I would secure a sponge or filter pad there.

    How many of you are successful with a nem in a mixed reef? I'm hearing cautions about it stinging coral and to go nem only. I was going off of:
    1. Mr saltwater tank has a nem in his reef. He says he let's it get settled and then adds Coral.
    2. Mark Levenson had one that he keeps inside a wall of death (his term) of dead sps around it so that it doesn't stretch further and kill other corals. It protects the other corals from the nem assuming it stays there.

    I only have a few coral in my DT now. A fair amount in QT. I was trying to let the nem settle into a spot before moving coral over. Do you think this will work?

    My Nem just tried to move 2 hours ago. It rubbed up against my Space Invader and the Space Invader opened its eyes threw out its tentacles and the Nem went right back to it's spot. LOL! Just surround your Nem with Space Invaders next time ;)

    OK, see you then. This one appears to be a good strain. I bought the original from a club member a few years ago. It has split many times since then. I don't cover anything and have had no problems with them getting into pumps of overflows. I have not noticed them stinging corals, but they will cover them. When that happens I encourage them to move by either using a turkey baster or small power head pointed at them. Once they find a spot they tend to stay there unless something in lighting or flow changes. They really like strong indirect flow. A clown hosting in them also seems to keep them put better.

    I take back what I said yesterday. I came home today and the Nem had won round 2 of the Nem vs. Space Invader war. We will not be having a round 3. Nem wins!

    Thank you Ben! I put him in the middle. He moved around a lot during the night. He finally ended up on the right in the lowest flow area. I'm hoping he stays there. Perfect but from where I normally sit. He bubbled up nicely. [​IMG][​IMG][​IMG]

    I can't wait to get my clowns in there. They come out of QT on the 21st. They were hosting a tiny rose nem where I purchased them, which they were loving to death. So I'm hopeful they will take to this nem right away.
