In Pet Culture in Richmond. They have many, but only saw one big one like the one I bought. Should be mix of males and females in that tank.Those are nice Rams. Where did you buy them? Anyway, some male do get pink belly but females do get dark pink belly to red. I myself have electric blue ram male with pink belly. How I know it is a male is because he had a fry with electric blue female. Good luck!
Oh well, I just keep my hope low then.What Rick said. I never use colour to determine ram sex, always the dorsal fin.
There are two fish in the video. I am talking about the bigger fish. Part of the video, I think I see the bigger fish has slightly extended front dorsal fin for the 2nd and 3rd rays. Time into video: 10-12 sec 39-41 sec and 1:17-1:25sec.It looks like a female to me. The best way to determine the gender on rams is by the length of the first few rays in the dorsal fins. Males (when mature) will have significantly elongated 2nd, 3rd and/or 4th rays like the one in this photo: https://www.livefish.com.au/media/c...95d7a28e8fd99b1b12aaae4bfab8/g/o/gold_ram.jpg
