your post about them is what got me interested, so thank youI just bought some a few days ago As they're my first ones, I can't really offer any advice. They're very pretty fish though, my are still juvies, and I can't really accurately sex them yet. When I was researching, however, a suggested ratio was 1 male to 2 females. I don't think this is strict though, just a suggestion. Are you buying juvies or adults?
that's good information to know. How many did you keep in the 10g? I was debating on where to put them after QTWhen I first got mine, I had them in a 10g quarantine tank for almost 2 months. They always seemed somewhat stressed in that size tank. They regularly had frayed fins and spent a lot of time hiding. After I moved them to my 29 gal, those issues disappeared.
I also had trouble getting them to eat flake food initially. I had to feed them frozen food, and gradually introduce flakes over a month.
My peacock gudgeons are apparently VERY sensitive to "contaminants" in the water. Even half-strength doses of Stress Coat, MelaFix or PimaFix would irritate their gills and cause them to flash violently. They just like plain, clean water.
Still, they're beautiful fish! Good luck!
