Definition of "tet"

I was on oral tet for months after I was first dx backn in '88. All I got from it was a very, very nasty and upset GI track. I had to stop it.

Tets are 44-chromosome conversions from 22-chromosome diploids, created by elaborate means involving colchicine, a chemical found naturally in crocuses. Only a tet can pollinate a tet, but some tets can pollinate themselves.

I've bought a couple of Greek tets that must have been dipped because all the toning is off them. They're white, but otherwise nice. Other tets I've bought have been cleaned as well but have more gray and other coloring and therefore look better.

All the tetras in my tank (3 species - black neons, Pristellas, and red eyes) died within a 36 hour period. The corys and otos in the same tank are fine.There was no change in water quality, feeding habits, or water temperature. I have no idea why all the tets would die in such a short time span.

“It's a tet shot,” Roddy told him, relieved. A tetanus injection was the usual thing for a cut or puncture wound on a horse.

The Genital part is all nervy; the Tail ſmall; and the Hind hath Udders betwixt her Thighs, with four Speans or Tets, like a Cow.
