I think 100 gallons is big enough for plenty of crazy cichlids, I have never seen a really tough jd though ,but I hear there out there???? I like red devils,jags, the buttikoferi are all sweet and crazy!
buttis are mean,chewed my dads JD's tail off.had to get rid of the butti the JD is still alive.i have a pic but the gallery is still down so i cant upload it
jaguar cihlid
red motag
green terror
texas
salvini
any pair of the above would work but any tankmates are going to get killed.
single fish
a single red terror would be great and they are mean
butti
trimac
flower horn
rd
or a community of
convicts
sajaca
firemouth
any other aggressive cichlids that stay under 6"
it wont be a peacefull tank i assure you and quite entertaining cos there will always be a territorial dispute going on somwhere in the tank.
