drarcon Posted May 10, 2012 Author Report Share Posted May 10, 2012 hey donny..good to hear from you ...as always had lots of air ...spray bar used..with 3 different air stones...and tank always filled about inch from top... Link to comment Share on other sites More sharing options...
DeadFishFloating Posted May 10, 2012 Report Share Posted May 10, 2012 sounds to me like the cannister was not running for a few hours or even over night....... and was then plugged back in. weird conspiracy theory, but that would produce ammonia and nitrite...... I think the thory of ammonia and nitrite coming from lost fish is more likely tho Link to comment Share on other sites More sharing options...
liss05 Posted May 10, 2012 Report Share Posted May 10, 2012 How are the remaining fish looking? Any heavy breathing or distress? Diet sounds great and water all sounds good so hard to know really... Link to comment Share on other sites More sharing options...

drarcon Posted May 10, 2012 Author Report Share Posted May 10, 2012 doesn't appear to be stress in other fish...no heavy breathing etc...the hongi are having there usual little battle but thats cool... Link to comment Share on other sites More sharing options...
drarcon Posted May 10, 2012 Author Report Share Posted May 10, 2012 donny sure does suck...... I guess this is also weird......you started my african journey over 18mths ago ....and those fish are all alive...including your tangerine ..really good looking fish... All the rings in bought from Aquarium Warehouse and others are now gone ..funny enough i am leaning towards my electrocution theory from the cheap powerhead i bought them ...i guess a hard lesson learnt RIP Link to comment Share on other sites More sharing options...
liss05 Posted May 10, 2012 Report Share Posted May 10, 2012 I didn't think fish could get electrocuted from faulty wiring in the tank? I put a second hand wave maker in one of my tanks not long ago and when I went to clean the tank I put my hand in the water and oh boy did I get a huge hit my arm ached for the next day turns out there was bare wires coming out of the wave maker but it never affected the fish they were in all fine it was in there for days before that happened to me It didn't affect the fish cause there was no earth for them? Was my theory anyway.. Link to comment Share on other sites More sharing options...

Was my theory anyway.. they cant be electrocuted unless they come in direct contact with live electrical parts. your theory on the fish not getting a zap is partially correct too, you got a shock because of a difference in potential voltages - IE tanks at 230vAC and your at 0vAC, because the fish they where at the same potential voltage as the water in the tank they wouldnt have recieved a shock. @drarcon - i doubt its from electrocution, i'm with DFF on this ,maybe somehow your filters been switched off, maybe you lost power, mini cycle perhaps, who knows, but the presence of amm and nitrite indicateds your filter isnt fully cycled or cant keep up with the bioload Link to comment Share on other sites More sharing options...
raycam01_au Posted May 10, 2012 Report Share Posted May 10, 2012 i hate bloodworm, did i say hate, yep blooodworm bad bad worm and that tank is and or was very heavily stocked with some random fish, of varying needs Link to comment Share on other sites More sharing options...
goneself Posted May 10, 2012 Report Share Posted May 10, 2012 ....thanks Ray. Electrical current in the water would need a conduit to earth, so unless you got zapped when you touched it, it wasn't that. Any chance the power went out at any stage? Even if it did, that many deaths from morning to afternoon is odd. Link to comment Share on other sites More sharing options...
Mackayman Posted May 10, 2012 Report Share Posted May 10, 2012 Hi Drarcon As per above posts, its a weird one. Im just wondering if you got some sort of strange parasite. I had dramas with my display a while back, turned out to be Trichodina, basically, something that can only be diagnosed by a vet. 3 month long thread here, may help. http://www.qldaf.com/forums/diseases-fish-care-water-discussion-12/persistent-parasite-49843/ Its just a stab in the dark, but may be of some help, hope you sort it out, good luck.

raycam01_au Posted May 10, 2012 Report Share Posted May 10, 2012 as much as your fish will love bloodworm and it seems to be a favoured food, you may find this was a contributing factor in the fishes "mystery" deaths, mbuna do not do well at all with bloodworm, and as stated thats was a very random stocking list in a small tank, so possibly an internal parasite, bloat, stress many factors in there to look at,,,,, .....thanks goneself Link to comment Share on other sites More sharing options...
goneself Posted May 10, 2012 Report Share Posted May 10, 2012 Are the electric blue that turned black and the vertical hongi from the same tank? Sounds like maybe there's been an issue there for a while which might have just kicked off today. Link to comment Share on other sites More sharing options...
drarcon Posted May 10, 2012 Author Report Share Posted May 10, 2012 Hey GONESELF...no didn't get shock from anything because anything in contact with water was switched off before the distressing haul.... i can't believe that a amazing parasite could activate itself on 8 fish in a 5 hour period...a time activated parasite ..although i do watch HOUSE occasionally and it happens...hehe everyone here is meaning very well..and the information is very much appreciated.. so thank you all Link to comment Share on other sites More sharing options...
drarcon Posted May 10, 2012 Author Report Share Posted May 10, 2012 goneself..maybe it those issues were a precursor to todays debarcle....those fish are still with me Link to comment Share on other sites More sharing options...
Wolfgang Posted May 10, 2012 Report Share Posted May 10, 2012 bloodworm dead can shoot your nitrate over the moon you have a carbon bag in your filter it will overload enough to change every twoo weeks from feeding and overstock of fish by the sound of it , my addvice remove carbon bag from canester replace with shell grit hang your carbon bag in the back somwere replace bag every 2 weeks hand in the sun to dry and you can use it again over and over ,charcol can only absorb so much nitrate to absorb moer nitrate it releases a different gas that will push you nitrate & amonia over the top very heavy aeration will also evartorate nitrate hope this helps and sorry you had this happent Link to comment Share on other sites More sharing options...
raycam01_au Posted May 10, 2012 Report Share Posted May 10, 2012 whilst house is a great show and yes i do not believe you had a super parasite worthy of a place in his show, take a look at bloodworm under the microscope, i would never feed my fish it, its like russian roulette, and as wolfgang has stated left uneaten or dead it can be toxic, as previously stated the mix of fish you have in a small tank was always going to lead to fights n stress, you have or had some very aggressive fish in there very capable of making life difficult and if they were stressed wiping out a few very quickly, there are many syphtoms of stress i hope all goes well as well as not liking bloodworm, carbon is also a evil u can do well without best of luck, will keep my eyes peeled out for a house episode soon Link to comment Share on other sites More sharing options...
aussie123 Posted May 10, 2012 Report Share Posted May 10, 2012 You tank has began to cycle over again for some reason and your fish have died from Nitrite poisoning. Their gills and blood will probably have a brownish look to them. Water changes will help and only salt can have a chance at reversing the Nitrite poisoning if any other fish are affected. 5 times the does in salt to the level of Nitrites can have a reversing effect on the poisoning. Unfortunately the level of salt often needed can knock the fish off anyway so its a gamble you sometimes have to take. Link to comment Share on other sites More sharing options...
