My mini shark tank

Many people actually don't set up this type of community as not really a popular setup but many of these fish are actually being mix with other fish in a community tank.

So here is a video of my expermental 39g planted tank with some labeoniaes in it. I'm still new to plants so my aquascaping skills is not yet the best. Still learning and still need some tips and advises. If this expermental 39g planted becomes a success. I'm turning my 180g and 120g with heavily plants setup.

I kinda have problems with my bolbitis though. The rest of the plants are growing and triving well but my bolbitis are turning black and leaves and turning brown. When I used to have them in my 315g I have no issue and the rhyzomes are growing but now I placed them in my this small tank and they seem to br dying.
