>>In a small tank there may not be enough space for the male to retreat to, and the female may kill the male.<< That's what happened to me. They spawned in a ten gallon with no problem, but the female killed the male shortly after the eggs hatched. So if you forced to go with a ten, then have plans to move the male if they spawn, even if you don't plan on breeding them in the ten. They might just go ahead and do anyway, regardless of what you plan <s>. Bill Vannerson http://ourworld.compuserve.com/homepages/william_vannerson
