We have 2 shubunkins(sp). The one has always been a perky so and so, the other slightly quieter but still fairly active. Today he seems to have spent most of his time in the tunnel thing. Almost motionless but not dead or anything. He came out for feeding and if 'roused' he comes out fine and swims around a good bit but goes back in again. What could this be about. I'm really nervous as these are the only fish we've had that have lasted longer than a fortnight. We've had the water checked, not overfeeding. Anything else? My god fish are such hard work!!!
