Before setting up my tank, the majority of people I spoke to said that coconut fiber would be the best substrate to put down in a 50/50 tank for my FBTs. I went ahead, laid it out and put them in. Less than two days later, the water is loaded with it, the FBTs are covered in it and so is everything else. Stupid question I guess but is this normal? I hadn't seen anyone else post here about how messy it is (I don't know why it didn't dawn to me that it would be.) I just feel bad for the little guys, they're constantly covered in it despite how often I clean the water & decor. Is there any other substrate out there that is better to use? I was told no coconut husk and no moss. I saw a few "liners" but wasn't sure if that was the best route either.
