The water paramiters is fine.. ammonia/nitrite 0ppm. Nitrate I have not checked.. by the time I do a vac and water change, they are faily deluted down.. I have 12 tanks running so not a concern really.. I did see one neon slow and he looked fine but was not their the next day, 5 to 4 now.. Their was a cory cat with them, but he is now in a different tank, unsure if he was the problem. the shrimp would not leave him alone. they were in a 29 gal but with so few now, I moved them to a 15 gal and they seem a lot better now.. I stil may find another place for the shrimp. neat to watch but I would like to add in some more Neons later..
Thanks all. just wondering if anyone had a simular problem..
