Pale damsels

[furni80]

Anyone have any idea why my domino damsels sometimes turn pale? It doesn't last long but curious why this happens. Thanks

Stress or asleep. Check your water chemistry and/or watch for bullying and disease.

It only last for 5-10 min. They were acting odd like chasing each other in a mating ritual or something. My levels are good except the nitrates are a bit high. They have calmed down and acting normal now. No sign of disease on anyone.

Sounds like typical Damsel behavior, chasing and agression is pretty much what they do. My favorite fish, but they are not passive.

Yeah they are definitely aggressive. Thanks for the input.
