CDM;2156920; said:Herrghh?? Really? And, the LFS sold it as a hybrid? There are two batch imported here, the former batch (my one) looks more like congicus, and the later batch looks closer to endlicheri. However, none of them look exactly like a congicus. I don't know what's going on there, the things are getting harder when there started cross breeding.
As for feeding feeders, yes, the type of food do affect the growth rate, that's why I said "maybe".
i see...
the lfs sold it as p.e.congicus.
the ones down here seem to look more like congicus and none of them look short body like yours.

Do you have a pic of those, or any links?
Well, that is probably because those bichirs came to your area probably are wild caught, and it's difficult to keep the external gills during their natural life/get caught/shipping process. I didn't see such well kept external gills few years ago untill they started importing the farm bred ones.
