Mystery Deaths **long post warning**

Hullo.

I was wondering if anyone could help.....

Back in August my partner and myself set up a 4 foot tank. We cleaned it thoughly, rinsed it out, put in 2 inches of gravel (that was cleaned as well), a couple of rocks and a big chunk of bogwood (soaked for 24 hrs and then rinsed).

We filled it up with water and ran it for 4 weeks without fish or plants. It has an eheim filter (no idea which one but was around £70) and a branded heater (the box looks like its from Miami Vice era).

After 4 weeks we put in 7 White Cloud Mountain Minnows and some plants. They were fed alternate days on flakes and frozen food. Water changes were 25% every Sunday.

After a further 5 weeks we added 6 Red Platies and some more plants. Feeding and water changes as above.

2 weeks later we added 1 Red Tailed Black Shark (he was mine) and 2 Clown Loaches plus some plants. Feeding/water the same as above.

Again after 2 weeks we then added 6 Serpe Tetra. Feeding/Water as above.

Then a week later I bought 2 more Clown Loaches.

Every time we added fish we took a water sample to the fish shop for testing.....all the levels were fine.

Everything went swimmingly :joke: for a further 5 weeks. My partners friend came round one day - both him and his father have kept fish for over 30 years between them - and he commented on how good they all looked. I had gone out early so hadn't seen them that morning. In the evening, around 4pm we gave them a block of frozen bloodworm, they all ignored it which was unusual.

I looked at them and they appeared to be gasping for breath even though the water was saturated and an airstone had been added a few weeks before, the Platies and the Loaches loved playing in the bubbles. I called for my other half as I was really worried. We took the fish out and immediatly did a water change but there was no difference after adding them back in.

So we turned out the lights and then my Shark hit the roof of the tank...!! about 30 mins later after we had both been searching on the internet for possible causes, we found the shark dead.. :( We immediatly fished him out and put him in a tupperware box. All the others were still gasping. The platies appeared to be nosediving, they were verticle with their mouths pointing into the gravel (eventually all the fish did that) then they went belly up. They survived belly up for about 30 mins before appearing to have one last burst of energy (or having a fit) and flying across the tank before dying.

It took each one 45 minutes to go....I could have set my watch by it. As each one went we took it out. The next morning (I stayed up all night looking after them and crying) we called several fish shops looking for an explaination. No one had any....they went through the ususal stuff...levels, visible diseases, etc. They all looked fine...well they had all lost their colours by that time but you understand.

One guy sugested that it might be high chloring levels and to check with the water board if they had been doing any work the previous week in our area. I phoned them on the Monday and they denied any work had been done.

So....all in all a complete mystery. We never had the fish autopseyed (sp).

Now I panic about my new lot ...we started over by bleaching the tank and cleaning it, threw away the gravel and the plants, we soaked the rocks and bogwood in salted water for 4 days then in clear water for 3 after that.

We now have 12 5-lined barbs in there and 3 female bettas. I am hoping to get another RTBS and Clown Loaches, the other "must haves" are an Upside Down Catfish (for him) and a male Betta for me. He also wants a Silver Shark but it could be a bit too much.

So...can anyone give me any idea what could have caused them all to go so quickly...? and will the new fish be compatable...?

Sorry for the long post.

Regards
Claire

sorry about the tank:( ....

about the problem, did you get all the fish from the same LFS?
If you did it could be that it was a problem with the fish, and not the water. they may have had a disease, some sort of parasite or something...

because of the fact that they didnt eat the bloodworm and tht ll the water levels were fine i would bet that it was an internal parasite or other internal disease.

as a side note...dont bet on the RTBS/silver shark and the male betta getting along too well (definite fin nipping)
 
Hi.

Err...yes. They all came from the same fish shop. It was recommened to us by 3 different people.

The weird thing is they all went on the same day. It was literally 12 hours from start to finish.

Really the RTBS wont get on...? damm. I have always wanted a male betta as well.

My RTBS was a complete softy. We had 2 tunnels in the tank and loads of plants, the shark had made the left one his...then the Clown Loaches kicked him out...so he went to the other one and the Platies booted him out of that one. The Minnows wouldnt let him in the plants so he used to stick his head in the end of the tunnel with the back half hanging out. Persume he though if he couldnt see us then we couldnt see him. :D

He was always getting pushed around. Poor thing.

Forgot to mention - we now use Tapsafe in the new water. We also clean (and did clean) the gravel with one of those tubes.

In the original tank the plants were growing at a heck of a rate. I was doing cuttings virtually ever week. In the new tank the plants aren't growing as quickly. Its been over 10 weeks and I still havent taken any cuttings.

There are 2 lights in there - one is for plant growth the other for fish.

They do get fed every evening with one block of frozen food just like the original guys.

Only time I've seen fish asping, at least in my experience, was when my 3 year old dumped an entire can of tetra flakes into the tank. That kind of thing wouldn't show up on water quality.

Ad for the shark/betta thing... it wouldn't be the shark who causes the problem. But when it happened in my tank, the shark definitely ended it (after ignoring the betta for a long time)
 
Your fish died from poisoning...though I have no clue as to what 'poison' it might have been. There are many toxins that are capable of wiping out a tank.

1. chlorine/chloramine(ammonia)
2. toxic metals(lead/copper/iron)
3. pesticides
4. houshold cleaning products(soap/glass cleaner)
5. overdosing of medications
6. unsuitable decor/equipment(naturally collected rocks or wood sometimes can harbor harmful toxins/chemicals)
7. manufacturing chemicals present in products used in the maintenance of the tank that weren't designed for use with aquariums(some plastics, garden hoses)
8. paints, varnishes, glues, dyes, and the fumes from such.
8. unsuitable plants(Dieffenbachia)
9. poorly stored foods can lead to aflatoxin poisoning(rare)
10. smoke, airfresheners, aerosol polishes that may land on the water surface.
11. excess CO2 gas
 
Poisoned...? erk.

There is a tight fitting lid on the tank that is always closed apart from at feeding time or waterchanged.

We dont use airfresherner in that room and the only other room on that floor is the kitchen and there is no fresherner in there.

There is a coffee table about 3 foot from the fish and at a lower level so it cant have been the spray for cleaning that...I dont think anyways.

The only thing it could be is if we had something on our hands when we were doing the water change/replanting afterwards. The water change happed on the Thursday and they went on the Saturday and the fish were fine in the meantime - unless it was slowly killing them.

We wash our hands under running water before putting them into the tank - no soap just water.

:scratch: I think its going to remain a mystery as to the actual cause/poison - just like the location of Atlantis.

Thanks for the replies.

Anoxic gravel can poison fish with hydrogen sulfide gas and/or methane, as well. But since your tank was relatively new, and the fact that you gravel-vac, I doubt that's what killed them either. One of life's mysteries, I suppose.
 
Is there an air pump running anything on the tank? If so, any chemicals sprayed in the room--even from a distance--could very easily have gotten into to the tank.

That was one of my suspicions, as well.

Claire, if you could remember what you were doing that day around the tank or in the room, that might shed some light on the subject. Also, if you could list all plants and decorations in the tank and where you got them. Hopefully, this won't happen again.
