One word, electricity. Making sure nothing is leaching current into your tank will go a long way.
Could be a number of things though, good luck.
Thanks, I will definitely borrow one ASAP and find out if there is anything leaching. I have done the roughest of rough tests for this (Hand in tank, bare feet on ground) and felt nothing, but that doesnt mean that there isnt anything.
WOW. Tagging along. GL. I'm at a loss but maybe inspect the dead fish for signs of anything?
I have had a couple of them, and found nothing, but I just tore the mouth and gills off my diamond goby, and it looked pretty normal throughout the gills. The top of the mouth directly under the brain, which may have been a see-through opening to the brain, was black. Not sure if that is normal or not.
This has been my downfall as far as being a responsible reef keeper. Its one of those things that I know is a good thing, but I also have gotten away without it for so long that I thought I was good enough at choosing healthy specimens... guess not.
did you add anything new?
I think the newest addition was a Percula clown from an established tank, seemed fine, but started showing signs of stress before death.. go figure.
tagging along. Added any new fish lately? Or anything new? Not sure if you have anymore fish in the tank, hope you do, but if you do and one dies, hope they don't, fresh water dip it and see if you may have fluks
I am a fish guy, so I have added fish. But not for about a week before deaths started happening.
I have 3 chromis, 2 fusilier's damselfish, a lawnmower blenny, and a melenarus wrasse, who if dies, I am going to be REALLY bummed.
I will freshwater dip the next casualty, it seems bound to happen at this pace. Maybe I should go check now...
from reading your thread, it seems like you don't qt and also added too many fish too soon. gl to you and hope you get it figured out and don't lose them all.
I know I added too many fish, and way too quickly, but the die off started about a month after the last "batch" of fish... there were additions here and there, but only singly.
Where did you get this info from I've not read that? If your referring to the fish i think he's talking about the order they died in
Its in my tank build thread "Xavier's 120 gallon Journal"
Hypoxia maybe? Possible phytoplankton bloom of Chaetoceros (slices the gills and kills the fish)? I had 3 fish die in 4 days last year with no indication as to why (all water parameters were spot on, and no disease or fin deterioration, no recent changes etc.) , all had been in my tank for about 3 years, while a 4th fish showed no signs of stress. These are wild guesses, but are some hypotheses that I have had in the past for mysterious die offs in my tanks. Unfortunately no remedies, just explanations, kinda. We all feel for you... but it happens
I thought Hypoxia, but I have an Algae Turf Scrubber that runs straight through air, and a skimmer that introduces a ton of o2. I also have a good amount of flow inside the tank. I have 2 Koralia 1050s and a K3 running. Is there any way to test for that particular algae bloom? That sounds like a possibility, or something of the sort.
Read through your tank diary, wow you've done alot and looks nice. My question is what about your green carpet that got caught in a power head, (" Green carpet got sucked up by a powerhead! I caught it in time and turned it off. Within the day, it had gotten itself out, and right back into the powerhead next to it!"). I've heard of things like this wiping out a tank. I have no knowledge or experience in this and I'm hoping someone else will see and answer this.
Thank you for the compliment. The carpet was chopped up, but it recovered almost completely 24 hours after each incident. It is completely possible that it had something to do with the deaths though, as it occurred shortly before this die off... I know that once they die they release toxins. I didnt know the individual tentacles have the ability to foul a tank as well...
Would this affect only fish and not corals? Thank you very much for your post.
Anemones getting sucked into power heads would be something to mention, if it was within a few days of the die offs... the Cnidocytes (stinging cells in the anemone) contain toxins that can (but not necessarily will) contaminate your tank. The anemone tentacles can also get shredded up, essentially spraying your tank with bits of anemone and lightly dosing your fish with toxins. If I had an Anemone sucked into a power head followed by a non disease related mass fish die off, I would attribute it to the anemone... but I don't yet know if the two happened around the same time in your case, so this may not apply to your situation. Just my two cents
See above. I think this may have been a factor if it is possible that it affects fish only.
