However, I've been reading, and realize that my substrate may not be appropriate for my fish. I've got two Orandas and one Black Moor. The substrate I currently have is the standard (small) gravel-like stuff.
- Do I need to get the larger, smooth pebbles/stones so the fish don't choke?
- If so, would I just lay them on top of the gravel I already have in there? I'm very nervous about doing anything that might upset the good bacteria in there (i.e, removing the gravel), as I've finally just got it where I don't have to do 50% pwc's twice a day.
Any advice would be greatly appreciated, of course!
