African_Fever Posted March 4, 2009 Report Share Posted March 4, 2009 Most people who've had motoro's for years recommend 48" wide for life. But with that being said, I think 38" would last most motoro's at least 5 years, possibly longer. They can have huge growth spurts and grow from a 4" disc to a 12" disc (and then 24" long) in a year and slow considerably after that. I use silica sand for my ray tanks (and all tanks for that matter), and I get frac sand from a local oilfield supply company for free. The sand doesn't need to be as fine as possible - I have some that's comparable to sugar and I think it's almost too fine and prefer a bit larger. When a ray buries itself or swims up the sides of the tank towards the surface there's a lot of force of water under it's disc, and if the sand is too fine it really blows everywhere and will get in everything (ie. powerheads used for extra circulation).
