One of my pleichotis did die, can't tell why - may be cold - looked
recent, no decomposition.

I'm guessing that's "plecostomus" - no access to taxa references here to
know if it's an actual genus. There is almost nowhere in the continental
US that a Pleco will survive in an unheated outdoor pond. S. Florida,
maybe Houston area - I've heard San Diego, so you _might_ just be far
enough south for them.
