I have an (under average) sized adult senegal bichir, it is the only bichir I would say should even be attempted. Usually the bichirs aren't something I would say one could keep in under 100 gallons, but the senegals I have worked with usually max out at 12 in (biggest i've seen was a 15.) The delhezi is a very common species where I live and if you see one It won't fit in under a 125, my smallest one is 14 inches and not yet full grown.What type of eel would you be keeping?
Also, i dont know a great deal about polys but is there a species that could be housed full grown in a 75?
Would love to see a pic of that delhezi. Ive never seen one get to that size before though some publications have suggested 16" as a max size.The delhezi is a very common species where I live and if you see one It won't fit in under a 125, my smallest one is 14 inches and not yet full grown.
You sure you thinking of the right species? They get confused wit endlis sometimes. I highly doubt them being much bigger than 14".I have an (under average) sized adult senegal bichir, it is the only bichir I would say should even be attempted.

I almost answered the op but it's from 2011 lolSenegal bichir will be fine in the 75, fire eel will outgrow 75 peacock and brown knife should be ok.
