Hi Joe! Nice to see you visiting out hereFruitbat said:I'm afraid that I must respectfully disagree with kentobismol's statement regarding keeping only two bichirs in a 75 gallon tank. You could easily house four of the 'smaller' species of bichir in a 75 gallon tank (Polypterus senegalus, Polypterus palmas subspecies, Polypterus delhezi, Polypterus retropinnis) along with a few other fish.

Anne even knows what type of plants to use with bichirsthat drumin guy said:haha. Awesome looking tank by the way. Those plants are awesome.
She's a plethora of data in regards to Polypteridae. I think she has more info than fishbase, if I'm not mistaken. Of course you have also seen CDM's tank shots. He has a "million" bichirs just chillin right over the top of each other. Funny now though is that my male 14" Ornate thinks my 10" Butterkoefferi is very sexy! I think these adoloscent bichirs are just loaded with "teen" hormones. My god, they just embrace each other all the time!!!
I filmed them, but couldn't get the video to work. If it was my 75 gallon tank, I would put about 7 bichirs in there. Two albino senegals, one ornate, one delhizi, two polli, and one more delhizi. 
Fruitbat said:Well.....let's see....I got my first bichir (Polypterus senegalus) back in 1971 when nobody in any of the local fish stores had ever seen one before....and I've been keeping them pretty regularly ever since. Currently I have over 20 bichirs (11 described species/subspecies and one 'undescribed' species - the 'Zaire Green') scattered among a number of African Biotope tanks ranging in size from 10 gallons to 100 gallons. I guess you could say that I have a little experience in keeping them successfully.
A typical 75 gallon (not a 75 'long') has the dimensions of 48" X 18" X 20" (or 48.5" X 18" X 21" if you buy an Oceanic brand). This is certainly adequate to house any species of the 'smaller' bichirs though I wouldn't try to put a fully-grown Polypterus endlicheri congicus in it for life. There is a faulty assumption quite commonly held that the interlocking ganoid scales of Polypterids makes them significantly less flexible than their snakey appearance would suggest. While it is true that bichirs aren't as supple as, say, a Mastacembelid 'eel', they certainly don't lack turning ability. So....the old adage about making sure that the tank is wider than the bichir is long really has no basis in fact. Even a large (24") Polypterus ornatipinnis would have no real difficulty turning around in an 18 inch wide tank and those in the 12 inch to 16 inch category would fare even better.
Intra- and interspecific conflict usually isn't a problem with bichirs. In general, I've found them to be relatively peaceful fish (with the proviso that there is always the particularly 'grumpy' individual out there that won't seem to get along with any other bichir). As long as there are adequate hiding places available I wouldn't expect there to be any difficulties between the fish themselves.
Water quality is, of course, key to keeping any fish alive and healthy. As hardy and adaptable as bichir are, there is no sense in testing their tolerances for poor water quality. Effective filtration is essential and I highly recommend regular weekly water changes in the neighborhood of 25%. With good husbandry techniques there is no reason that four (or even a few more) adult Polypterids of the smaller species couldn't be kept in a 75 gallon tank.
