i was there yesterday and saw at least 5 lungfish, i think africans the biggest one was about 2' and they were really cheap around $40 or $50 i think if your in the area check em out or give them a call the number is (559)438-4343
I haven't been there in awhile. They probably have the best selection of fish in the central valley. I just ordered a 8"-10" lung from my local pet store for $50. Should have checked Whitie's first. Did you happen to see any peacock bass there?
