Hi, I have 55 gallon tank with a senegal bichir and one jack dempsey. they are both under 2 inches. I was wondering if i could put 2 of my 3 inch bolivian rams in with them. Right now the two are in a 20 gallon tank and they constantly bother each other. Their only other tank mates are 4 guppies that i had just purchased today. One of the rams even tried to nip at a guppy.
