"The Turquoise Rainbow Fish is relatively easy to care for. They can withstand a wide range of temperatures, but should be kept in water in a range between 68 and 76 degrees Fahrenheit. The pH level of their water should be slightly alkaline, with a range between seven and eight. Min tank size 20g keep 2 females per male." Yep it seems a reasonable dither fish for multies
(bit big though at 4") ?
I use zebra and pearl danios but then each to their own. :thumb:
I always thought the Rainbows, if given an environment according to their own needs, needed more swimming room than a 29G. And plants for cover. I know a lot of people use them successfully as "top swimmers" with Malawi, so they are compatible.
