What Are The Fish Doing ?

[jua]

I have 2 Harlequins in a 55L planted tank

This morning they are just swimming under the filter and nowhere else

They never really did this in the past.

Their colours are fine etc

Are they just resting or do you think they are hiding from something ?

 

[Harlequins]

What other fish have you got?

Harlequins do much better in shoals of 6 and upwards,ideally 10 or more.

Agree with harlequins, In small groups there will be very insecure and nervous. I'm sure in a bigger group you will certainly see a difference.
