If one was planning on sticking with amazon fish...., what do you think would be a better choice as far a a mid-water fish went. Something like a Dat..., but form the amazon. I like to try to keep it as real and as native as possible..... what about "Geo's"...., I dont have much experience with them but i have seen them used..., what does everybody think. Also are they hard to get or expensive...., I assume they are from the amazon...???
