I have a 3.5" Delhezi and a 6.5" Senegal who is much larger by mass. It looks like he could if he wanted, eat the smaller Delhezi but i have seen smaller and larger bichirs together before. for now i have the delz in a ten gal. by himself for a growout, the sen is in a planted 20 long growout for a 55. could i put both in the 20? or will the sen eat the delz, and i just keep the in the current tanks untill i put the sen in the 55 when he gets larger then move up the delz to the 20? i hope this isnt to confusing. thanks
