I like Delhezis and Endlicheris, but I've only been able to keep Senegalus' while I had my 75 gallon. Then again, I wouldn't dare put a Endlicheri inside of a 75 gallon long.
so hard to choose just one. out of the ones i own i'd have to say either my del or my new platinum sen. looking fwd to keeping some lower jaws one day though.
