I am pleased to announce that all 36 of my cardinal tetras in my 55 gallon are tank raised specimens from florida. My first batch I got 1 yr ago and I didn't read the tag close enough but they were tank breed. Went back today and got 15 more. Talked to the lady that runs Wet Thumb Aquatics (www.wetthumbaquatics.com) and she only buys tank raised cardinals. They cost a whopping 1.25 a piece. I always wondered why my cards did so well in ph 7.0- 7.5 and total hardness of 9. Maybe it is because they are tank raised. They have just as nice of color, and I have never noticed any differences. They school tightly but are not timid at all.
