I am moving my 155L tank to a new 155L tank (new glass) and cannot choose a suitable substrate that would be good for my plants AND good for my horseface loach.
He needs a fine gravel/sand for burrowing etc so does anyone have any recommendations? I didn't want to have to use sand, but something no larger than 1-2mm would be ideal as he siphons the gravel. I also wanted to avoid layering substrates too if possible.
Thanks in advanced!!
