Has anyone here ever raised shubs? If so when do they spawn? I have a few in a 125 gallon tank (for the winter) and it looks like they are either picking on one fish or some kind of mating ritual......don't know. Seems to early for them to spawn, but I don't know how being indoors would effect there timing either......is it possible?

is the water smelling very fishy ? it tends to smell awful just as they start to spawn ..

That is partially correct. The act of spawning causes the odor.
At DrDaves Koi, last years spawn occurred here on April 26th and the actual spawn lasted 8 hours.

I just wonder if bringing them indoors for the winter throughs off there biological clock?

My breeder Koi have always been kept outdoors. The spawn varies from year to year by about 6 weeks. I don't know how many people who would be successful in keeping full grown Koi indoors. We are talking about Koi that are 16" or more in size. It would take a very large indoor vessel for that to work. If they only had a male/female pair, that might work out.
