Here is a video of my Maccullochi rainbowfish (Melanotaenia maccullochi "Stark River") flashing. Includes some slow motion action:
Interesting. You should get her a new boyfriendVery nice. I think I have a female. I bought her last year at a petco because they had them on sale and ..just felt sorry for the last small fish in the tank for some reason. She's now well over 3" and for some reason spawns regularly with a large male. M. lacustris. Much more often then with the female M. lacustris.
No,I don't raise any. It's just fresh eggs for the botias and barbs and what else in the aquarium.
