I've been looking at these fish for one of my own tanks, along with a couple other species of blue eye. My reading points to 2-3:1 F:M ratios, top swimming schoolers. I'm not sure if they've got the tendency to hide in plant masses like pencils can.

Gertrude's Rainbow

Hi,

Gertrude's Rainbow, Pseudomugil gertrudae, is one of the 15 species that make up the ‘Blue eyed’ family. They are cute small do best in heavily planted tanks, though they really don’t hide out unless frightened.

I do not believe they are ‘true’ shoaling, certainly not schooling fish, they do well in groups. My experience s that they are mid-level inhabitants, they do best in groups of six females to two males, they are bottom spawners in a species tank you will have babies. They spawn continuously.

Gertrude's Rainbow, Pseudomugil gertrudae by Joe Kaznica and Pseudomugil gertrudae are a couple of good sites.

Philosphos if you are still looking in November I will no doubt have lots.

hi!
thanks for the info... how many fish in a 55 gallon tank? 6 are good enough so I can see them?
I already have rodostumos and rasbora arlequim and neons (and some cleaning ones)....

You will see them, they usually don't hide if maintained in well equilibrated group. They are very good swimmers. I kept the furcatus, one of the most beautiful and interesting behaviours of the family I think. I sold them because I had only a 60gal (120cm long). I think they will show their potential only in +150cm long tanks. If you see them in 100-120 gal tanks, you'll understand what I say :)

If you unstock your tank, you could try them for a while to decide by yorself

Something important, they won't live long in acidic soft water like your other fish, but they will still spawn if maintained in specific

Yes.:)

I like quarantine, so maybe some time.;)

In a well planted tank they should do well.

there is no problem to make babies of a yellow male with a blue female or otherwise? that was the main question here...
I love my small (so small really) yellow gertrudae.... I'd love to have more 6 blue ones... :)

Hi,

They are not supposed to, but I am not so sure. I have a few I do not know quite know where they came from.:rolleyes:

Pseudomugil signifer may help.

I know most problems revolve around tank mates that are too aggressive and feeding. They really need a robust and varied diet.
