Nano Fish For Hard Water

[daizeUK]

That's reassuring, I see so many of these nano fish are recommended to feed mainly on live food and I can't get live food every day!

Daize- if interesred here is a list of the blue-eyes:
 
Pseudomugil
 
connieae
cyanodorsalis
furcatus

inconspicuus
ivantsoffi
majusculus

paludicola
paskai
pellucidus

You can get information by species with good pictures from the links here. List is on the right side of the page- scroll down to the Pseudomugils http/rainbowfish.angfaqld.org.au/Melano.htm
 
If you would like free pdf copy of an excellent book on rainbows- more than most folks want to know- click here- it loads slow but is full of great info and photographs: http/ttp/peter.unmack.net/tappin/Rainbowfishes.2011.pdf
 
One note, while many of the tetras can take hardness to 15 dh and some to 25 dh, they tend not to like higher pH levels. If you want info on them  look here and scroll down http/fish.mongabay.com/characinae.htm

Thanks for the info TTA!  Very interesting book on rainbowfish.
I saw P. mellis and thought it was simply gorgeous but sadly it's rare and one that prefers acid conditions.  They say it can adapt up to pH 7.5 but I wouldn't dare try it at pH 8.2.
 
Mongabay looks like a good resource for finding pH & hardness information.  Much appreciated!
