Recently picked up a new bigger sump for the 135 and decided to utilize the center section as a refugium/growout. Would it surprise you that the first fish in the new growout was another poly lol. Had a baby endli in there within 48 hours of setting it up. Currently have 1 endli and 2 kolibas all around the 3-4” mark chilling in the sump along with a group of mollies/swordtails/guppies and some convicts to breed as feeders. Little monsters are chowing on massivore, tilapia and whatever of the feeder stock they catch so hopefully they grow quick! Since I’m trying to use the growout as a refugium for nutrient reduction as well it’s running a grow light so the pictures are all a little on the pink/red side but the fish don’t seem to care.
