All the more reason to just start off with a group of wilds. They're not that much more then tank raised or F1's of the same size and you don't have to wait 3 years for your males to mature from fry. Then again, it sure is fun watching them grow up too. It's a horse a piece, depends on you're taste I guess.The chances of 15 (or even 5) different sources of frontosa having something mislabeled or otherwise erroneous is extremely high. Get fish from someone who's knowledgeable and knows what they're doing and you'll be great.
