Hi;

I'm upgrading my tank & redecorating - I noticed some of the tanks in the stores have a really fine gravel, almost sand. Has anyone used this? Wouldn't it get swallowed? Would it get sucked up the syphon when I clean?
I've had my taricha for 5 years and I'm sure her tail is still growing, which is why I got a new tank. Is there some point where they stop getting bigger? Just wonderin'.

Thanks
