Hi @Biota_Marine I have a group of 7 pavo damsels and as I was walking past the tank today I noticed one of the largest damsels had large white-ish lines. When I took a closer look the lines almost immediately disappeared as the group reformed thinking they were about to be fed.

I was curious if this might be spawning behavior or if it's something you've seen before?

Thanks!

Hey Jimbo, this definitely could be the beginning spawning behavior. With damselfish a lot of them have intricate color patterns during mating that are actually invisible to us so it can be hard to tell when they're communicating in this way. The photo below shows what we see vs what the fish are displaying to each other. The next thing I'd look for is for one or a few of them to clean up an area for eggs. Being that your Pavo are likely pretty young it could be a few attempts before the eggs are properly fertilized.

Thanks! I caught him/her doing it again and tried to take a picture standing back from the tank a ways. Its really hard with my LEDs to get a good photo as my phone does not like the flicker but I thought it was interesting. You can see the largest one turns a very dark blue in comparison to the others and the light patches appear across the top. As soon as you move closer to the tank it changes back to the brighter blue and the patches disappear.

Just thought it was interesting and worth sharing!

What percentage of blue versus white lighting do you think makes the best coral growth combo?
