I recently saw a discuss for sale at my local pet store I've been setting up a 55 gallon tank and am in the final stages of setting it up (just need to plant it) I am already doing Cody's and kuhli loaches I was researching about the discus and came across the video on them and was wondering if I would be fine keeping a single one in my 55 with the bottom dwellers and maybe a few tetra, guppies, or gourami (probably going with the guppies or neon tetra) most places I've checked have all said a group of six in a 75 to 100 but a few have said that one or two should be fine in a 55 i would probably just be going with one if it would be fine by itself
