I'm wanting to use some pool sand filter sand in my tank. I know it will be fine for the geos and cats i have in there but I just got a great deal on 13 clown loaches. So the question to those of ya who have kept cl.. Do they like a sand subtrate? Atm they are in a tank with florite / plants. I want to do sand with the big java fern mother plant in the back corner. (few nice sized rocks here and there also) Thanks in advance
