up until monday, bichirs never interested me much for some reason. then out of everything, a little 2-3" senegal decides to come front and center in the tank and start hamming it up while at the LFS. i cant stop watching this thing now. slithers and swims around quite often, extremely active and cool looking. just when i thought i was going thru hobby burn out 
havent been this happy over buying a new fish since my rays. i havent started doing much research yet however on much other than a senegal, as im not sure what i want/can be mixed.
will i have to worry about any problems mixing different bichirs? if not, what ones would do best in a 250g with say 1 or 2 calmer cichlids?? was going to get another one in the tank of a different species, but it looked like his gills had feathers oming out of them, which ive now read is normal for juvi's?? and finally, sand is an acceptable substrate for these guys, correct???
