Hi everyone, I had a question on whether or not two occelaris clownfish would go after two Bangaii cardinals in a 20 gallon long aquarium. The clowns are currently in the 20 gallon and the bangaii cardinals are in a 32 gallon Biocube. My main question is whether or not that if I introduce the cardinals to the clowns that are 1 year residents in the 20g that they will either fight or be territorial. Clowns are about 1 inch and the cardinals are roughly 1 1/2 inchs. There are also plenty of hiding spots in the 20g with live rock caves and overhangs
