Red Rainbow Fish

Info on red rainbowfish Glossolepis incisus -
Active swimmers so need a tank at least 120 cm/48 inches long
Need a pH over 7 and hardness of 10 to 20 deg (179 to 356 ppm)
Shoaling species, needs a group of 6 to 8


They are not known as fin nippers but their active swimming will stress any slow swimming fish in the tank.
They need to be in a bigger group than 3. Their DNA is programmed for them to live in large groups, so keeping  less than 6 to 8 will stress them out.

And stressed fish means fish that easily get sick.

To be honest the fish profiles on here are a bit out of date and/or incorrectly written many years ago (errors do occur in even the best sources  ). There are plans afoot to update them but it is a slow, laborious task.
