What would be better for guppies and mollies, gravel or sand???
The tank currently has light coloured gravel with a mix of coloured rocks. I`m thinking of changing this to sand but not sure if both these fish type will like it.
Any comments? If sand is ok to use, what would be a good sand to get? If sand is no good I`ll just change the gravel to a dark coloured one.
Cheers, Min.
