I have a large amount of Caribsand leftover from my saltwater reef tank remodel and I'm wanting to start a Frontosa tank and would like to know if agranite sand is safe to use with these fish or if crushed coral would be the safer choice.
I use crushed coral but agranite would be fine. If it was in a saltwater tank make sure you clean it somehow. The make a grade of agranite thats large then sand but not anywhere never close to crushed coral. I think it would be a good idea to do a mix of the 2. That way it will be easier to clean and also you dont have to buy all new. I think the grade is call pea something.... Its just like really coarse sand.

Have used both of these items in my Front tanks & it works well. The only thing I would say is that coarse substrate can tend to wear the long trailers off of your mature males, it did mine.
