Yea, google will basically tell you anything you want to hear/ see- channel cats are very fast growing at first and often often top the charts at over 3 feet- not recommended for hobbyists OR standard home aquarium set up... I sold a group of channel cats to a hatchery for $650, they were found abandoned in a creek on my research property. I'm afraid of draining the pond and finding a wales cat lol. Cory cats are kind of like dwarf loaches/ botia, the naenus cory is probably the most commonly seen, at pet chains they are usually found with glofish and guppies. If there are any shops in your area selling channel cats you may want to check on the legality of owning them.
