I've learned that bicolor blennies are strange fish. They seem to get along with everyone until a certain point and then they go after everyone. I got rid of mine for that very reason. At about the 3 inch length mark he started to get quite territorial (ie. the WHOLE tank was to be his). Weird that it went after a specific firefish though. How do
you tell them apart if they are the same size?
