#1 *slaps your faces* over the sand and gravel. Theres no other substrate here.
#2 he was the only one if there were more i would have taken more. He was in a tank labled bichir just like that. Ive been looking carefully at any tanks labled bichir or dinosaur eel or anything lately in my local petsupermarkets because for some reason they have been getting good polys and labeling them as the whatever for cheap. At one store they had a label that just said "palmas" for 7.99 but apparently someone got there before i did. So im on the look out.
