Why did it die

  • We are currently upgrading MFK. thanks! -neo
Main thing is do a water change and clean your filters, you probably need to do it anyway if you haven't yet. Add a spray bar for extra oxygen. Doing any of this to cover all bases won't hurt. So do it all and make sure the rest of your fish are happy. My condolences.

Really?

Shakes head :wall:

Maybe a little more time on learning about what happens when canisters or any filtration that does this will do to a tank. If you buy that lack of O2 to the main tank will kill whats in the tank, then why cant you buy that the same lack of O2 in the filter is even worse..

It can and it does happen.

Just stating from my experience, having the canisters off over an extended amount of time, with 8 hours being the longest, wasn't long enough to kill my fish or get them sick or cause a mini cycle.

Youve only been here 5 months. Don't tell me to spend more time learning. I fully understand the chemistry behind nitrification and how nitrifying bacteria works. It would take more than not servicing a filter for 1-2 weeks as posts in this thread indicate to cause this type of damage unless the tank is horribly overstocked/under filtered in which case you have other issues to worry about.

Thanks for your awesome insight. But this is almost definitely due to no oxygenation for 12 hours. Op also said his parameters were 0/0/20, indicating he didn't have his tank under filtered and his filters likely weren't too bad. Try reading the thread before posting next time. Kthxbai
 
If would guess I would say that you had a spike in ammonia because trycolor sharks are very sensitive to ammonia. I once bought a hole school of them when I first started keeping fish hardly ever did water changes put them in and they were fine,came back from lunch and they were all dead. expensive learning experience

Just because someone has only been on a forum for 5 months means nothing. You have no idea how many years of experience a person has. A forum is no judge of a person's experience or knowledge.

Where in this thread did you read the op hadn't serviced their canister filter for only a couple weeks? Last I read was that they installed it and have never serviced it.

Here is the big question for the op. Did the death happen after or before the power came back on? Were your fish gasping before or after the filter came on?

Wow this thread is out if control... Some of the people are trying to help the OP but are just arguing between themselves. The part that is blowing my mind is some of the people keep claiming to have a solution with no proof of anything, and are not being respectful to other people's opinions. I personally do not think anyone truly can identify what has occurred because I presume none of us was there and is getting the full story. We have no idea the size of the aquarium, what type and brand of filter, how large the fish are that is in the aquarium, the frequency of water changes, how long he has had the filter and if that is the only filter, if the fish was ill before or showing signs of distress before the occurrence, were any of the fish distressed or as distressed as the fish that died, maybe the other fish was more tolerant of changes to the environment, and the list just goes on and on. Some of these questions were not even addressed and some people seem to just be assuming conclusions with not enough evidence, nor information. I think I have noticed maybe one other person being respectful and actually saying my condolences. I am very sorry about your fish. :(

I do not think the length of time a person has been an active member on these forums or Monster Fishkeepers is necessarily an accurate reflection of a person's knowledge. An example is a person that had been an active member for two years and has began fish keeping for as long as he has been member, and a fish keeper that has been in the hobby or even profession for 30 years but only has been an active member for three months. Now which has the most experience and is the most knowledgable? No I am not trying to lecture, but I simply just do not agree with that biased assumption.

I understand your point somewhat but are you sure you are conveying your point effectively? Just seems a little bit harsh.

Just to add my 2 cents.. Bacteria in filter start diying about 6 hours after power loss..i believe that after 14 hours without power,filter is dead - or if it isnt completely dead, it gets massive overload of bio waste when turning on again so filter crashes...in this 14 hours there was lack of oxygen and building up ammonia.. And there is really no need to clean canister every 2 weeks unless you have super dirty tank..

(sorry for my english,its not my first language) :)
