Do Kuhli Loaches need sand substrate?
Oct 17, 2010· I have a 75 gallon, well planted aquarium (java fern, anubias, swords) with driftwood, that is well established (2 years) that houses neon and cardinal tetras, bleeding hearts, 2 bn plecos, a pair of blue rams, and 5 ottos. (I am well understocked, and like it that way). I would love to add several kuhli loaches, but alas, my substrate is gravel.
