Hey everyone...
We have slowly lost our school of Cardinals (only 1 left now

)... They have all seemed to give up, just lay down on the sand bed and die slowly... we remove and quaratine them as soon as this happens. What we have noticed is a long white strand between the first and second set of fins on the underside of its body. I would say it is just waste but it stays for a day or so before disappearing almost like the fish is constipated. What do you think? Possible a disease of some sort. This is only effecting the Cardinals and nothing else.
I will also try to uplaod a photo but my camera doesn't take the best Marco photos.
