first here is my current 10g
4 harlequins
6neons
1 chinese algea eater
this is my new 38g
the back of the tank/ornaments will be filled with more gravel, the drift would will be almost even with gravel behind it, and the lava rocks will be a bit higher as well as the centre ornament. and then the back will have enough gravel for a few live plants.
the only concern i have is if when i raise the ornaments/gravel, especially the centre one, the inlet for the filter will be hidden behind it. just wondering if that will be ok? or should i modify the inlet.
