It is really nice to see them when they were young. Thanks for posting the picture Jim, and thanks again for these beautiful loaches.
This morning has been interesting. Two clowns, an SAE, and a kub crossed the water bridge during the night from the 300 gallon to the 75 gallon tank. It makes one wonder if the changing hierarchy because of the added rostratas induced some to leave. The first video shows the rostratas in the 300 gallon.

Jim, they are certainly enjoying exploring their new surroundings. They are literally all over the tank and out in front a good deal of the time. They are beautiful fish to watch. Is the following behavior a rostrata behavior? They sometimes stop on the bottom and wiggle backwards just a little bit (two or three wiggles and they back up about a quarter body length). I have seen my new little rostrata do this in the quarantine tank and also the large rostrata have done it a few times. I have not seen any of my other loaches do this.
This second video shows a battle in the 75 gallon tank that has been going on for at least 4 hours. They are both greyed out. It is between the kub that just joined the aquarium via the water bridge for the first time in about two months and the other loach (the bigger gravid one) which I bought as a kub, but looks more like a rostrata (since it has not developed the horizontal black stripe)? They do not seem happy to see each other.
