Have not used the prazi pro - is this a better courseOops I just saw you haven't treated with PraziPro. I thought you did. So nematodes are not the only thing left. But I would still look at dewormers and suspect nematodes if the metro doesn't seem to help.
So it was the Hex Shield they weren't eating well?
And what about the medicated bloodworms, eating, not spitting? I watch the fish for a while to make sure they don't spit. I don't know how long you feed the Metro for, just make sure not to feed too long or use too much. I hope you see some improvement with them.
I noticed the smallest holding food/or a turd in its mouth then spitting.
day 2 of Meteoplex - treated the tank -
they all are eating - some much fatter than others -
