I have had a couple live bearers die since yesterday and they are getting this weird opaque fuzzy film around them. What is that?
Could be- I suggest a large water change- your ammo and trates are high- I think you might have triggered a mini cycle when you added your fish...
That could be a mini cycle but I thought that the nitrate levels are ok as long as they are under 20. I didn't think platies and guppies would be that sensitive to fluctuation.
The fish deaths stopped. I think I just bought them from a not so great store. I won't be going back. The fuzzy film appeared postmortem.
I did a 60% water change with the gravel filter tool. Fish seem to be happy and healthy.
Thanks for the replies!
