Actually the top pic you posted with the royal clown, that catfish has many long bars on it, not just spots, and if you look closely on all the big corruscans, you can see white vertical bars along both sides of the fish.
In the second pic, those fish look like a hybrids or some other catfish of some sort. Look how short and pointed the nose is and look how long the soft dorsal fin is. the one in the front is definetly not a corruscans. The one in the background is hard to tell, need full body shot.
Only time will tell how my fish will look as they get older. All I know is that I have had many TSN's before and these are much different.
