would a 8-9" BGK be ok with 3 4" cichlids and 1 7" geo.. I have 2 bichirs in there with the cichlids and they leave the bichir alone... Tank size 55gallon...
What kind of Cichlid are we talking about? The others would be fine. If it was a JD or Oscar, probably not a problem...maybe a Convict or a Jewel would pick a fight...Doviis and Jags would kill the BGK.
