If you love Tetra Embers, here is a video of them entering the aquarium (20.04.2013) and from the next day, when the school was already very beatufil.
Their colors are not as nice as they should be in the future, but nevertheless a very good looking fish.
I think music is very nice for the images
In the aquarium set-up video I saw that you didn't really plant a lot of HM, but how did it grow so much? Probably stems acting as horizontal runners?
No, just trimming. I just replanted a few plants in the first trim.
For each trim the plant will be more "bushy" because it starts new plants form the local of the cutting. HM doesn't make horizontal shooters.
