Well, I appreciate your help very much. And I like your daughter. lol I'll shop around at a bookstore when they open today.
Totally forgot to mention any of the books my daughter has. Her fav one does have a pretty decent section on corys. It's all around a pretty good book. "The Ultimate Encyclopedia Of Aquarium Fish & Fish Care" by Mary Bailey & Gina Sandford.
Thats the one she likes to pick a species to read about every night. (She got mad at it however because the other night she found it didn't have anything on Electric Blue Rams -they were developed in 2009 but the book was published 1999- Silly child)
