First post on here, awesome site. I currently have a 55 gal setup with mixed africans, a friend wants to give me a Jack Demp. My africans are in the 2.5" to 4" range, the jack is about 4". Just wondering if you all think this will work. The mix I have right are: bumblee, kenyi, ice blue zebra(i think), cobalt blue 2 yellow labs,a jewel and one I am not sure of. I know some people do mix, just wanted some opinions. Thanks
