Tank Collapse - What a sad day....

About 2 weeks ago I changed skimmers as my chinese one was not doing a satisfactory job. The resulting improvement in nutrient extraction was enough to rouse my H. magnifica from it's spot about 5 days ago. I have been in this hobby for 20 years an have successfully kept 2 magnifica during this time. This one was 3 years old and stable at around 20 inches across in my 300 G display tank. In had not moved for 30 months and looked exceptionally healthy with full, fleshy tentacles and a beautiful vibrant body. It was a poster child of H. magnifica and sat in my mixed reef happily.

The movement of the anomone up to the bank glass of the tank was cause for concern but the animal remained looking healthy so I took the opinion that as long as its movement stayed within close proximity of its original resting place, it was unlikely a significant concern and did not justify the risk of trying to peel the foot off the glass which can harm such animals. So I let it do it's thing.

This morning, after the regular 9 am feeding, the anemone was positioned where it normally was, high on the glass, far from other corals and looking healthy. I was hopeful that the disturbance of changing the skimmer was subsiding and i would return to a static position on any of the bare rocks near it.

3 hours later, my fiance asked my what was wrong with the tank. I had been in another room and when I came quickly to look my worst nightmare had happened.

The H. magnifica must have released to wall and had been pulled into an mp 40. It was shredded by the pump and the result was a very macabre scene.

My foxface, hippo and yellow tangs and 2 blennys were on their side taking short desperate breaths. The tank was a thick milky opaque color. I quickly scooped out the troubled fish but they had a nasty deep red tint through their gills. After a desperate 40% water change in a 45G tank I use as a QT tank for new arrivals, I delicately got the sick fish into that tank.

Unfortunately, this was all the water I had on hand. I only keep 40Gs of RO water at a given time and at this particular moment I was low as I had been working on my auto top off system this week to work out some small bugs in the kalkwasser-mixer. I got my blue throat trigger in there as well but no other fish were visible (or remotely accessible) in my DT. None of the fish were looking good; they were quasi-catatonic with no movement except the quick short breaths of very stressed fish and all )except eh bluethroat) had big red stains in their sides which you could see through their skin.

My next move was to run to the store and grab 20 water bottles (18.5L ones for water fountains); these had acceptable impurities given the situation and I rushed home with my 300 litres. I drained my 90G sump completely and filled it again with the store bought water. 15 mins later I had 1.025 fresh water ready to go although only at 68 degrees. Since I had 1200 watts of heaters in my sump (I sometimes let my apartment get cold in the winter), I let the heaters bring the water to 70 degrees and then started circulation with my makeshift QT tank and the fresh sump water. After about 10 mins at 500 gph, I decided that the qt tank had as clean water in it as I could get so isolated it off from the sump (it has it's own canister and heater) and then recirculated the sump with my DT.

So I had basically new water in a qt tank and the fish looking rough but away from the toxins produced by the suicidal H. magnifica.

2 hours later...

All fish in the QT are dead. The desjardins tang, the hippo tang and the yellow tang are dead. MY foxface is dead, the 2 blennys are dead and the bluethroat is dead. I buy my fish young and small and these are all fish except teh foxface that started not much bigger than a dime and that I have fed everyday for 3 years. My hippo had such an enthusiastic and great personality as it frequently would come and display itself to any curious on lookers even after a feeding. I will really miss these fish and I am deeply saddened and remorseful of what has happened to them. My mistakes today were paid for by their lives and I have lost a lot of friends today which is very hard; I am very sad about it.

After 20 years in this hobby I'm finding this to be my worst ever disaster. I am sure that my other 10 or so fish that I couldn't reach in my DT are dead as the ones I managed to get into QT had the best chance of survival.

Even now, I cannot say that H. magnifica are not a reef safe animal because I have kept them for years and years on end, my other one I had for 7 years before a move ended its life.

This recent loss of life is just horrible and I think the purpose of my post is to add to the many horror stories on this site and perhaps the sharing of my experiences will benefit someone.

Fundamentally, I took a risk with an animal that can be risky in an aquarium and the results were the worst case possible.

Maybe anyone reading this will remind themselves to take the time to fix those small tanks issues, and complete the redundancies in their systems so this doesn't happen to them. Maybe I'm just trying to give a reminder to be careful with their tanks. These systems we keep are so delicate and accidents like this are too easy to let happen through neglect, carelessness or even perhaps arrogance. After having a H. magnifica for so many years, I never thought one would decide to walk into an MP40 and kill my tank. I really never thought that would happen.
 
SO sorry. Many of us who've been in the hobby a long time have been through something not identical, but equally out of the blue devastating. I feel for you.

The only thing I can say is make the next one better. And best of luck in doing it.
 
That's awful! I'm a longtime mag keeper as well, and always worry about that happening to my tank. I've designed my tank so that it's difficult for the anemone to 'walk' into my vortech pumps, but nothing can prevent a 'floater' unfortunately. Not had one release like that myself, but probably just luck at this point. I suppose some kind of cover would help, but they are so ugly (or reduce flow) to the point they're not worth it. Keeping a large anemone is unfortunately not without its risks, and I think the general recommendation not to keep one is wise for most reefers. So spectacular though .....
 
My deepest sympathy. I know how hard it is to lose your little friends. It sucks. I recently had a heater malfunction, the results of which were a loss of over half of my livestock. I cried my face off when I saw my blue spotted jawfish with agonal respirations, his tail being chomped on by crabs and a brittle star as he lay dying. When I explained what happened to a friend of mine who is a long-time reef keeper, he said that if it makes me feel any better, fish don't feel pain like other animals.

This brought me a little comfort as I felt that maybe my deceased buddies didn't suffer as much as I had imagined. I hope you can find some comfort in this as well.

I truly hope you don't give up any aspirations of starting over. Remember the years of joy you experienced with your tank, and only one bad day, albeit a REALLY, REALLY bad day. I know many people enjoy keeping anemones, however my gut tells me they are more trouble than they are worth, so I have settled for a very large, very beautiful Orange tube anemone which I made a "home" for out of PVC pipe and buried it in my sand bed. It is perfectly happy there, and has never attempted to move.

I am very sorry for your loss, but try again.

Thank you for the kind words guys. I'm very bothered by this collapse as I really thought my system was safe from such disasters. After so much work ensuring redundancies on every essential piece of equipment I really didn't expect a suicidal animal to be a cause of such a calamity.

Happy reefing and I hope your days are better than mine.
 
that was one of the hardest and saddest things i have ever read on this site. i'm really sorry for the loss of your fish. :(
 
My sympathies. I had a similar crash a year ago and it was devastating.

I lost all but four fish in my 165 gallon tank. Honestly, if it hadn't been for the survival of those four and some of my favorite inverts , I'm not sure I could have roused myself to start over. I did, though and now I'm glad.

Best of luck.
 
I had a BTA end up in my Jabeo in '13. I'm assuming it happened right before I woke for work because I was able to get it out, do a huge water change, and have everything back up and running without losing anything else. It was purely a case of dumb luck that I caught it that early and I truly sympathize with your situation (I pretty much lost my entire aggressive tank about 20 years that had a clown trigger I had nursed from slightly larger than my thumbnail). It broke my heart and I completely understand what you're going through. Sucks feeling like you let something down.
 
Thanks everyone again for the kind words.

I highly doubt at this point I'll ever give up the hobby. What has been so painful this time is that this was my dream system. I dumped the necessary cash into a very strong and stable system. After having seen so many spectacular tanks through this site and others, I have always aimed to achieve the the quality of the TOTM systems and really thought that this time I had a real shot at a truly spectacular display. I had great coloration and growth out of all my sps and lps and about 40 varieties of sps in there with a happy and healthy fish community.

It just blows to build your "perfect" system after so many years of learning and realizing better ways to do things. I thought I had it down this time and now I'm almost back to square one.

Update: All my fish except 2 true perculas are missing or dead and my dt has that wonderful aroma of mass die-off. I've completed another 50% water change but the damage to my DT has been done. Time for a month of algae blooms and high nitrate water to combat as the tank deals with all the dead bio-mass in it. Many corals have yet to open up and have their defensive mucous barriers up. I'm not really worried about them but I still expect some corals to not pull through.

So, the final result is 95% fish death resulting from the H. magnifica dying even though it was removed from the tank no more than 2 hours after it entered the mp-40. The consequences alone of that happening are seriously shaking my belief that H. magnifica are safe in a mixed reef as even with 10 years of stability; this can happen and it will kill all your fish...

Given how fast and properly I was able to respond (even having a qt ready and available); I doubt that it is realistically achievable to keep that animal without this being a possibility. I'm not saying every H. magnifica will do this but the pump was not even close to the anemone. My tank is 6' long and the pump was on the opposite side of the tank to where the anemone had resided without movement for 3 years. I can't see how this can be prevented with 100% certainty in a tank and I guess it's just a risk that must be taken if people want a H. magnifica in their reef.

I love that animal and with my success I can't recommend to anyone not keeping them but this is the result of taking that risk and losing and it's horrible.
 
So sorry to hear about this. Since you attended to the death of the anenomie so quickly, I assume it had no chance to decompose and starve the tank for oxygen or produce enough ammonia to kill anything. Is that anenomie known to release toxins when it dies? Were the fish poisoned or was something else at work? Thanks for the write up, you very well may have saved someone else a lot of grief.
 
Terrible news. I had an aquarium crash a few years ago and in less than a day lost everything. Start again and enjoy it. I'm glad I did.
