About to lose a rainbow?

[walt8880]

Yesterday I bought 6 small Praecox rainbows and put into my tank. Yesterday and this morning all six were shoaling together.

Suddenly this afternoon, five are together and one is hiding in the corner behind the plants.

Is this normal behavior or is that one likely sick or has been cast out of the shoal for some reason??

Thanks

Just keep an eye on him for now. A hiding fish is sometimes sick, or weakened.

Whenever I see something out of the ordinary I always go for a partial water change.

I did 80% water change the day I put them in.

They're back together this morning. Maybe he/she was just tired and taking a break.
