Hi everyone, I'm a newbie and would love some help and advice. My tank has been setup about 3 months now. The first batch of Neons I had got something I was told was Cotton Mouth. I purchased Furon, took the carbon out followed all the instructions, did the water changes but they didn't improve. I ended up getting rid of them and starting again.
I then got 5 Neons, 3 Plattys, 5 Runny Noses, 1 Betta and 1 Alge eater over a period of a month or so and I thought all was going well. Then 3 of the Runny Noses died and the alge eater within 24 hours. I did a water change, tested everything and 24 hours later they appear to have white spot. I took a sample of them to the fish shop and am now treating for bacteria and white spot. 1 Neon has since died and 1 of the 3 Plattys is clearly unwell and being picked on by the other 2. He's hanging out at the top and appears to be having difficulty eating.
The shop tested the water and couldn't fault it, I have taken all the advice I have been given and asked lots of questions.....they told me it was just bad luck! Am I missing something? Fish and medication is getting costly.
Any tips would be appreciated.
