many people keep bichirs in large groups and they tend to pile. as long as many hiding places were provided i just don't see a reason they would be overly stressed if they do well in giant groups in bare bottom tanks
guess that makes sense never really gave it that much thought just figured there would be more negativity around it if it was that bad on em. most i ever had in my 75 was my del, a pair of sens and a young palmas polli. now its just my del and im lookin to order 2 more upper jaws, its not something i would do i just assumed as many people do it and don't get flamed it was considered fairly common practice/acceptable
To the op,i would say if you wanted all of the ones on your list,look into a tank that has a wider foot print then a stander 75gl like 4x3x?
You will have a happier bunch of polys,
Good luck and what ever you do go with post some pics

Well a lot of times people are afraid to offer any criticism. You always stand the risk of someone blowing up in your face for speaking up on the behalf of the animals, or they don't realize it's a problem when there is one. That said it's understandable to fall into that trap of "Well others do it and no one throws a fit so it must be okay". The best thing you can do as a fish keeper is research your animals. Where do they come from? What is their natural habitat? How do they interact? Then you take that information and use it to make informed choices as you look at the information people give you about the animals. You take other people's experiences into account but you cannot forget their nature.
To Sanguinefox: Can I kindly ask you, how many bichirs do you own or have in the past? Very curious. Thank you.
