    hi,

    I have a 30 gallon, liquid carbon, flourish, medium lighting tank..

    it cycled properly, and I added 12 cardinals and two gouramis after a month.. they were fine..

    later I added 4 mollies, 6 guppies, 6 dinos .. and right after my fishes started dying..

    now dead - 4 mollies, 2 guppies, 3 cardinals, 2 dinos ..

    I am doing my water changes weekly 30% and giving sparse diet to fish ..

    what is wrong?

    What are your water parameters? What filter are you using?

    Did you add all of those fish in the second part at once? If you did, that could've caused a mini cycle. Also, I'm not sure, but it seems overstocked to me, especially since mollies are very poopy creatures. What are you parameters?

    Could've also been bad stock though.

    I'm thinking the same thing, tank is overstocked with the mollies in it.

    You really should have your own test kit and not believe the test results of lfs. Adding too many fish at a time can cause ammonia spike.

    Good morning,

    Until you can post readings for Ammonia, Nitrite, Nitrate and pH, it is really difficult to say what is going on with your aquarium. I hate that you are losing fish. I know it isn't easy to stand by and watch them pass especially when we do not know why.

    Anytime something seems "off", a good place to start is with a water change and adding Prime water conditioner.

    If it is within your means to purchase a test kit, I highly suggest the API (liquid) Master Test Kit. This kit will test for everything that you really need.

     

    Each test can also be purchased separately. If you go this route, I would suggest starting with the Ammonia Test Kit.

    Prime Water Conditioner:
     

    Best wishes for your tank and fish and I hope you enjoy the forum. Please keep us posted.

    Welcome to Fish Lore!!!!

    I agree with what the others have said so far, water parameters would be very helpful. Also, I do think it's quite possible that you got an ammonia spike from adding in all those fish at once, especially because mollies and guppies are high waste producers.

    Good luck! :)
