I have two pairs of GBR's, one pair in each 20g and they are doing great, im getting spawns about every month or so. I also have a male GBR in a 29g community. Im wondering if you can keep multiple GBR pairs together in one tank? If so what would be best like 2 trios, or 2 pairs, 3 pairs etc...
Thanks for any info
