I also agree both males. But IME the darker one was the stressed out fish. and the lighter (normal colored) fish was the dominant fish. 2 GT males arent the greatest tank mates. I had to rehome my second male due to him getting his ass handed to him and almost got killed.
Hmm, ok.. I hate how it's so difficult to sex them when they're juvi's.. I guess I'll have to bring one back and get a female, hopefully they'll make a good pair.
