no worries man, R-tards are all over the place and will forever infest your life. If you learn to just lol and say "ok man" now it will make your life easier later on down the road. I had a lady argue with me today saying that semi-auto and full auto weapons were the same thing. I just laughed and said "ok", and it sent her to the moon.
Sounds like that guy is a egg, that is most certainly an ram, not a oscar. A oscar is much bigger than an ram, but a oscar and an ram is both an cichlid.
Perhaps you should spend more of your time at school studying grammar instead of talking about fish...
I sold my second tank to a guy last week and I asked him what fish he keeps and he just said Cichlids and nodded his head as if I should know exactly what fish he is talking about.
