I am aware of the sexual or asexual thing, it's the variances between species and hearing different experiances.
BTA's are known for splitting, and that can easily be induced, and some talk of nems budding, leaving a small bud of nem.
Some have asked why my sebae or LTA have never split in 5 1/2 years, and some say they don't split, then someone comes on here and says that theirs did.
When looking at another LTA and thinking 2 colors mixed would look nice, I've been warned that 2 together may spawn, and may spawn regularly requiring heavy WC's.
And now here we are w/ someone saying theirs is spawning all by itself, and in 5 1/2 years I've never witnessed this w/ mine, and while it's extremely healthy, it's dealt w/ temp changes/param fluctuations as well.
My point is it seems when we think we've got these guys figured out, something new comes along, or someone has a very different experience than others.
