Dead Fish

Postby thefishman » Sun Sep 02, 2012 8:07 am

Hi Guys,

I added six plants to my 64 litre tank last night and added Tropica Plant Growth Specialised Fertiliser and Easy Life Easycarbo as discussed with san-ho-zay on the plants section of this forum.

I did a water change after I put the plants in, mainly to get rid of any bad stuff that was floating around the water after moving the gravel around. This morning, three of my danio's are dead and one looking very white lying on the gravel under the filter. The last danio (only 5 fish in tank) was under filter but comes up for a swim very occasionally.

Ammonia has shot to 1 on the API Master teset kit with Nitrite at 0.

Apart from going back to very regular water changes until I get the ammonia sorted - what should I do??

Thanks,
The Fish Man

That isn't good!
Having never used either of the products mentioned I don't feel I can offer advice but would say to do at least 30% water changes daily until the ammonia is 0

Unfortunately the last two Danio's died on Sunday sometime during the day - only found them when I got home in the evening.

All the fish I've had in the tank seem to die very suddenly. My girlfriend keeps some fish also and only cleans them out once a month (and I mean fully cleans them out) and doesn't have any problems. I tend to leave the filter alone and carry out water changes once a week and gravel say twice a week and have all the problems!!

What can I do to try and stop this from happening?

Why do the gravel 2x a week? That is overdoing it in my opinion and I wonder if you disturbed some anaerobic bacteria (although I would have thought there would not be any if you were cleaning that often).
How long had you had the fish? Perhaps they were genetically weak?
You can't compare what you are doing to your girlfriend as your tank sizes and stocking levels may be different for a start.

Hi,

Sorry gravel clean once every two weeks - hopefully that's the right amount??

What is the best way to keep the bacteria growing in the filter when I get round to getting some more fish?

Must have had them for 3 months or so. One died within a few days of getting them then these five died within 12 hours of each other but I haven't done anything different.

Thanks for your help.

It all sounds very odd and I would suspect perhaps something on the plants, or products used (unlikely though), that caused the problem.
Is it possible you had something on your hands when you planted the plants?

The gravel cleaning you are doing is fine.

If you mean keeping the bacteria going in the filter until you get more fish, a pinch of fish food daily ought to do it. Make sure you test the ammonia, nitrite and nitrate before adding ore fish.
