I was just wondering how fast a senegal grows and how much one about 8-9" should cost? A lfs about 1-1.5hrs away has an 8" one for $25, but I was debating driving to get it b/c it's big or should I just buy a little one from PetSmart for like $7? It's only about 3" though. If they grow slow, I'll probably just go get the big one, thanks.
