Hi I have recently been suffering with mass fish loss which has been over the last few weeks, I have been to my local pets at home for advice and they have told me 3 different things for each time I have been down and I believe they haven't got a clue what there talking about, firstly I have a problem with algae as my fish tank is in a conservatory this was just a small tank at 64 litres so heat was also becoming a problem but I have since bought a fluval Roma 200 so that the water won't heat up much more than the temperature I have set it and it also has a much bigger external filter which keeps the algae at bay but my fish are still dying infact I lost 8 just today all that is in my tank is 5 sword tails, 20 guppies, 2 plattys, 2 Corys, and a plec, it has only been the guppies dying with the excepting of my Siamese fighter last week, there symptoms seem to be various different things some lose colour in there tails or back end, others seem to have swim bladder problems and some look like they have a small case of fin rot. the ones with the swim bladder problems don't last 12 hours and I just don't know what to do anymore I have tried allsorts and could really do with some help and advice please
 
Check the temp of your water and get yourself a test kit. Make sure you don't use cleaning products to clean the tank
 
My tank had been set up for 5 months and I don't use any cleaning products, I took a sample of water to the store n they said there was high levels of ammonia, but the water has been changed over time since then also they are now in a bigger tank with an external filter as the one in the smaller tank wasnt great
The temperature did rise in the smaller tank but now there is over 3 times the amount of water for the conservatory to heat so it hardly changes at all
 
Okay, it sounds like your tank isn't cycled. Get yourself a liquid test kit that measures ammonia, nitrite and nitrate (also get pH and high pH for later on).
Once you've got that, post the results on here. You're most likely doing a fish in cycle so check the beginners resource centre in my signature.
Have you changed any of your filter media lately?
Also, your number of cory's should be 6+ as they are a shoaling fish.
 
Ok thanks for the advice and the media wasnt old when I got it as I bought the bigger tank off somone else and they told me, I shall buy some more Corys but not until I've sorted this issue, ill get a test kit as soon as I can and post the results straight away thank you
 
Try not to think all Pets at Home colleagues are like that :p

Yes - for sure don't add any more fish, you will only make the problem worse.
As Blondielovesfish says, take a good read over the Beginners Resource Centre - you'll find you'll learn a lot and quickly.

Good luck! :)
 
I have also been considering buying a uv filter would this be advisable or not thank you
And I don't think all pets at home staff are all like that just the ones at my local one there are others a while away and they have helped me great in the past :)
 
I wouldn't waste the money at this current moment - get this problem sorted first.
 
Not sure if I mentioned that some of my fish seem to be going green? My silver Molly looks like it has 2 faint green lines down it's side and it's tail is starting to tinge also a cory has this green tinge in its scales around its gills? Lost another 3 guppies today also had my water tested and everything came back fine? Really lost :s is there any parasites or bacteria that could cause neurological damage and then death?
 
Everything was fine he had ticked the minimum box on the sheets that pets at home people do ha
 
Yes the box that says "water quality" - should be explained to you. I am a Pets at Home person as you've probably guessed.
Any progress on getting your own kit?
 
I would advise to do daily water changes (at least 50%) since you don't know how high your ammonia and nitrite levels are. Fresh water could be all that's needed to prevent any more fish deaths.
