Hi my ranchu is in a 50 gallon tank and he seams to have clear poo mixed in with some green. In addition to that he sits at the top of water for a few minutes each day. He doesn't look or act sick other than these 2 things. The tank is cycled and he is only fish in there. I was wondering if anyone knows the cause to these things or if it is normal. I feed him solient green and peas. I feed him 2 times a day and the size of a pea and a half. If anyone can help I'd be grateful. If anyone needs a picture Just ask.
