Okay in my shrimp tank I have a MLP and it looks to be slowly dying and I want to change that, I think it is my PH being 7.4 and it not being out of the shade, so I moved it right inder the light, It has really nice roots, and is in plant substrate. also I have a really, really, crappy filter. that is soon going to be changed, to a penguin bio wheel 150, becaus, well the other one just plain sucks. Also I heard they can suffocate from floating detritus, is this true?
