I had 2 in my tank (it was a 48G at the time). They were fine together for quite awhile (a year or so) then I noticed that one was getting noticeably larger than the other and would chase the smaller one when it got too close (pretty much as soon as it came out of hiding). They always slept together at night. The chasing was getting pretty bad and I thought I may lose the littler one due to starvation as I was having difficulties target feeding it without the larger one scaring it off. Then the larger one croaked. Now I have one happy little firefish.
