I have two 10.5 inch oscars. One is an albino red and the other is a tiger both are very colorful and healthy. I will download pics when i find my camera. They have been going through multiple mating rituals for a while now. I finally put a flat piece of rock inside the bed that they have made. Now the tiger has a long milky colored string hanging out of him/her. It fell off and floated into the filter. My question is, has anyone ever seen this??

first of how long have you had them,reason i ask is they can breed from around 7 inch,and from what you said id say it was fish poo?
