Piggy,
Congratulation !
If they fight with each other actively, should consider the critical moment has been passed.
However, from the photos it seems that your tank is too open for shy fishes. I think your tank is sitting right in between your dinning room and living room. right? Actually I can see a door at the back of your tank. Even open and close the door, those fishes will be frighted.
For this case, the most important thing is to create shelters.
"Iron Crown" is a easy choice as they are pretty "rough". If you don't like grass, wood or rock also do. A place should be created that when a fish is inside, it will not be disturbed by any external movments outside the tank.
Hope it helps.
If you like a "clean" tank, give the "Holland Phenix" to me and change other fishes like "Moon" which is not shy at all.
Enjoy !
