My sister does not believe in real research for her fish she believes that aquatic calculator website is the best thing in the world and totally accurate. So today she told me she has returned all her guppies and tetras and picked up an acai cichlid, a red zebra, and an auratus. Her tank is 27 gallons. She crushed up her coral so she could keep these guys, but I'm worried that they are not suited for her tank. It should be around 75 gallons, right? Research I've seen says that some of these guys are fairly social and need small groups of each species.
What do you guys think?
