How many bichirs?

For the bichirs you could probably add a couple more if you wanted to. As far as the other stock I am not that familiar with other than the fire eel and the BGK and I think you should be fine with them.

I've heard that the prochilodus can suck the slime coat off the Poly's the way plecos do but I have no personal experience.

Not synodontis, prochilodus. From what I understand they also eat algae like plecos so they literally suck slime coat. I found this out BC I wanted to get one for my tank but found they might not be compatible with Poly's. YMMV

Synos suck off slime coat too. It rarely happens but I had a lace syno and he sucked off the slime coat of del.

Why not get the tank and then worry about it? Get the largest tank with the largest footprint you have room for. Then ask this question.

In my experience with synodontis and polypterus, the syno will suck the slime coat off but only if they are not fed correctly or starving but there is always the chance of one just being an --- towards it's tank mates. Same goes with Plecos not all Plecos will suck the slime coat off a polypterus in my experience it goes back to being starved or lack off food.. But in saying that ask MFK member Rodgers what a Pleco can do to a polypterus.

Fire eel and geos will do fine. The BGK will be 50-50 depending on how often u feed your bichirs and how much. Also the size of the BGK as well the size of endli, ornate, polli and weeksii. If all bichirs are at the size of 10"+ and the BGK at below 10", it could get eaten. Unless u can make your BGK grow fast to 15-18" but that will take years and most likely it will stay at 10-12" and slow down from there. Ornate, endli and weeksii will get to 14-18" in a year. Also all 3 get a potential size of 20"+, no hope for u on keeping BGK with those 3 bichirs. Takes about 5-7 year for BGK to get pass 12"+. Those 3 bichirs will take 1-3 years to pass 20". If u really want a BGK, special order a wild caught that is around 13"-15"+ as at that size they are more robust and and even a 20"+ bichir wont be able to swallow it.
