If you are going to be in the Urbana-Champaign, IL area, check out Pets Ltd. as well. It is on Cunningham in Urbana. It changed hands in December and the new owner likes Apistos and always has a few. Every time I go there I am sad because I have no more tank space for the new Apistos he gets in! The only problem is that his supplier often sends him unidentified Apistos and since I am new to the hobby I have a hard time identifying them. But the plus side is that he usually sells these unidentified fish for under $5!
On a side note, if you are going to be in the Urbana-Champaign area let me know and we can get together if you want! (I am a student at the University of Illinois at Urbana-Champaign. You can contact me off list at: firstname.lastname@example.org
