I’m looking for recommendations on how to stock my 20 gallon tank in a visually pleasing way. I currently have 3 gold rams, 1 koi plakat betta, 6 celestial pearl danios, one super red bristlenose pleco, and 4 schwartzi cories. I would like to have a setup where the colors of the fish complement each other and it seems that some of them are clashing now. Any recommendations would be very appreciated!!
