They usually grow about 12" long, they do breed pretty readily, and most texas are very aggressive and a lot of times like to claim almost the whole tank as theirs, although there are some exceptions but all mine were total b*tches. They arent very picky eaters, you could feed them earthworms, pellets, various other clean live foods, frozen foods like krill, you might be able to get them to eat peas and they also love feeze dried foods. I would suggest you house them in a 75 minimum or say like a 100 for a pair.
