HI, gotta 48x20dx26h 100us gall tank comming any day now,along with twin eheim 2217s, like to keep either a oscar or devil/midas alone as a family pet,Got 6 kids in the house and would like something for them to have an interest in also, as my other showtank is a bit boring for them(Mpimbwe frontosa colony+b tricotis)my tap water is med hard 7.6ph. the tank will be sited right next to my sofa,Anyone got an opinion on whether the devil would be more enjoyable,or will he frighten the life out of my little ones?Leaving the oscar as the best option!Im happy with either though!Your views please!
