Hey I'm new to dat's but my lfs has a NTT 3'' but they can get any Dat with in reason they said? My question is can datnoids get along with african pike or will they attack and harass them? My african pike are 5'' but I know the dats will get bigger when they are both full grown. I have a 300 gal 8' tank with bichirs and a irwini. also how many dats could I get and what species do you recommend.
