Right now I have 1 del and 2 sens. I am looking to add more to the collection is there any rule on thier agression? Can upper jaws live with the sens and dels? Or can all species co hab together I know some grow much large then others.
 
Certain species are more aggressive.

Some people say lower jawed species get aggressive around the 16" to 18" mark.

The only aggressive Polys I have had an issue with are Ornates, they bullied most everything, but they were also around 17".

I have kept everything else listed in my sig together just fine without any aggression.

Right now I have a 17" Koloton, 15" Cong, 2x 12" Delhezi, 2x 15" Tikiso Endli and a 17" Ansorgii with 0 issues.

Sens and dels are upper jaw :p all upperjaw bichirs can cohab for the most part. Mixing lower and upper can be tricky but as long as there isnt a huge size difference it will be okay

kk then i would say if you wanted to add some more upper jaws try and get them in the size range as the ones you have now. But If you want lower jaws then i would wait until you polys are around the 7-8" range because lower jaws grow considerably faster
 
I have an ornate with lapradei. None bothers each other, my ornate is the most lazy fish I've ever seen, it hid under a rock for 2 weeks straight without moving an inch. I was afraid it was going to die so i chucked sinking pellets at the "entrance" of his little tunnel. Now he's fat.
 
Thanks for the advice guys ill try and add an endli next within the next 3 weeks.
