After houres of watching bubbles badger pearl my husband and i came up with an idea of getting a tank divider well after an hour or so trying to fine one for a 125 gal and came up with this makeing a tank divider ourselves out of pvc pipe and Plexiglas we pondered that for a while
6 to 8 suction cups small to medium with hangers are reccommended pet screen NOT METAL plastic pet screen is what we used i guess u could use reg plastic screen depending on your o cut the screen to fit measure the side or your tank and the highth leave an extra inch or so to burry the bottom
makeing the divider

lay the screen flat cut to fit tank measurements attach suction cups to sides of divider this is y we used the pet screen found at your locale hardware store or walmart. reg screen is too thin make sure theay are going all the same way and the hooks too bend the hooks so theay are closed so that the screen dosn't slip out once all are smashed take and make a well in the bottom of the tank all accross moveing all rock possable attach suction cups first on one side of tank to be divided if theay wont stick clean the tank glass on the inside attach other side and burry the bottom in the rock straightening as u go if u have little fishies like we do in with the o's cut an in or so off the top so theay can have full access to entire tank while the bully is on the other side
