Brought my water in today to get tested... I have a test kit but I brought it in since I was going to look at the ray. They said I have another 10 days- two weeks and should be all set.
Hes talking about the poop. If your ray poop is dark, solid and curly, then your ray is healthy. If your ray poop is white, runny/stringy, and breaks up into peices then your ray has internal parasites.
my ray's poop look like a back donut that someone took a bite of .. it is C shaped thick and black .. thats how it should look .. if you see anything but that you might have a problem .. but not always ..
