I`m getting alot more female `sthan male`s

Anything I can do to change this to get more males

Thanks

Hello Fredmir,

What are the pH, GH, KH, and temperature of the water in the breeding tank, please?

Thanks!

Hello George,

The above water parameters are perfect for breeding Nanochromis transvestitus! In the absence of any documentation that links sex ratios of fry to pH in this species, I don't know what to tell you. Sex ratios of fry in some Pelvicachromis species are linked to pH, but I've never heard of nor experienced the same causative phenomanon in any Nanochromis species.

Perhaps others reading this thread can share their experiences.

Good luck!

Go for a lower ph, of around 4.5-4.8, I've heard they prefer below 5 for a better ratio.

Hello George,

CDawson may be on to something. The guys who originally described Nanochromis transvestitus reported the pH of the water from the type locality (Lake Mai-Ndombi) at 4.0. However, maintaining a pH under 5.0 in aquaria can be tricky. Please watch out for crashing.

Good luck!

sex ratio - my experience

I have been breeding transvestius for about 2 years now, pH 4. Perfect sexratio, 50/50. Half a year ago I used tap-water when changing water. After a while the pH was about 7. In the following brood I could hardly find a single male among the 50-60 fryes.
