Trying to phrase this without X words.

I think one of my Schubunkins is about to have off-spring. I used to have
aquariums many years ago, so understand what is involved. Are Schubunkins
live bearers? Should I put her in quarantine, i.e. acquarium? Our pond
(bucket) is only 100 g, populated by three Schubunkin and four Koi. I
expect most will be eaten....
