any tropical fish experts here?

Just set up a tank for my daughter, allowed it to run for a couple of weeks before adding 3 tiger barbs, within 10 hours 2 had died. We then went to a different local store to ask for advice and buy a water test kit. When they heard where we got the fish they were convinced that they must have been a bad batch as they had heard of problems from this place before. Rather than buying a water test kit they gave us a few more tiger barbs to see how they faired and suggested we bring in some water to be tested.
Overnight 2 more have died, the water has been tested and all levels are within the correct levels. Everything else appears to be correct so really not sure whats going on, i'm going to leave things as they are for a couple of weeks and retest the water before buying any more fish. Any help or ideas :lease: as to what could possibly be wrong would be most welcome.
Many thanks
Ian :smashin:

Tiger barbs are quite aggressive in amongst the pack, and will fight and kill others.

Try some tetras, for example neon tetras, maybe a handful of them, and see how it goes.

what water test kit did you get , what temperature is the tank ......

i read it that they only had tiger barbs ....

Hi. Temp is 24 and the test kit was an off the shelf job that the store did, not convinced that the tiger barbs have been on a murder spree but will not rule anything out yet. We have a couple of neons too and they seem ok... thanks for the help guys..

was it a liquid test kit like this

how did you cycle the tank , i suspect that the tank hasnt cycled and the filter isnt doing its job correctly , have you rechecked the nitrite and ammonia levels , they need to be zero or else fish will die or not last long , if you have a paper strip test kit then bin it and but a liquid test kit , they are far far far more accurate ....

Hi, it was a tablet in a tube job, ph was fine and the nitrate was about 25, whatever that means? when checked against the colour code thing on the box it was within limits. If you say the nitrite and ammonia need to be zero then this could be the prob, it makes sense. The tank was set up and left to run for about 10 days but with no fish or plants. Whats the best thing to do then Paul? i'm thinking to leave it for a couple of weeks and then retest and do a 10% change of water in a week. We have 3 barbs and a couple of neons in there still but i 'm sure they wont last long. Is there anything i can do to help get these nitrate/ammonia levels down?
Many thanks for your help

Nitrate is fine , its nItrites and ammonia that needs to be zero , ideally I would see if I could get the fish rehomed and then do a fishless cycle with ammonia , if not then you need to get used to doing large ~ 50% water changes everyday to keep the levels in check , slowly but surely you will build up a colony of good bacteria in your filter and you will be good to go ....

when doing the water change do i need to put the tap safe stuff in? and i presume that i have to try and match the water temp? i.e add very luke warm water, sorry if this is a stupid question

I would do 50% yes , try and match the temperature , you do know at most you can only have a handful of small fish in there .....

I would also go to another shop as they should have asked those questions and advised on ammonia/nitrite. Leaving a tank running with no fish in it achieves nothing. You need to feed the filter to start the nitrogen cycle and you can only really achieve this properly by adding pure ammonia (available in Homebase) before adding fish. Once the tank is cycled using this 'fishless cycle' method, the filter is ready to cope with fish waste.

If you know anyone with a tank, get some filter media and add it to yours. Your filter will probably be ready to accept fish instantly. I have done this for friends and also did it to my own tank with filter from my brothers and it worked perfectly.

I have found Seachem Prime to be the best value dechlorinator: Seachem Prime 100ml £6.49 - Buy Water Conditioners Accessories

There is a way of speeding things up , use some filter media from an established filter , do you know anyone already running a fully setup tank ? ......

my wife tells me she looked at the results of the water tests and says that they were all fine, so really not sure about it all now, sure if anything was overly high and dangerous the test would have shown this? ive just done a water change so hope this will slowly begin to help

Which tests? It is nitrite and ammonia that is most important. I would keep doing the water changes just to make sure.

hi dave, i'm confused! is a dechlorinator the same as adding ammonia? should i use both or one or the other? i used tap safe when adding the water which seems to be the same stuff as you suggest..

It is the same type of stuff , so let's not worry about that at the moment , unless you are going to remove the fish then forget about adding ammonia , you need to keep the ammonia and nitrite levels right down so the fish survive but the filer grows ammonia and nitrite munching bugs , hence the large frequent after changes .....
