HELP! My neon tetras have a white cottony growth on their mouths. Is it ich? Only one of them had it and suddenly now 2 or 3 have them. What can I do? Is it contagious. Shall I use Melafix?
1~My tank parameters are:
Nitrate - 25ppm
2~ The tank is 180l. It's a Juwel Rio and I am using the Juwel 3.0 filter that came with it
3~ The fish I have are noted in my signature here. They are all adults. The tank has been set up for 2 years
4~ I did a water change a few days ago. I usually do 25% weekly and am very disciplined in doing so.
5~ I added some new decor a few days ago but I made sure to clean them in water thoroughly before. I also added some plants. I usually add excel or flourish every 2 days.
6~ I feed the fish a variety of tubifex worms, vege pellets & two varieties of flakes
