white thing on birdnes, pest?!

[Alitoo_81]

Hi I was searching for the red bugs to see if the interceptor did the work and I didnt find any red bug :dance:, but whe I looked to the birdnest i saw something white and It bothered me again. do you know what it is???

I thought it was a nudi or some kind of pest so i cut it out and i decided to take a closer look with the micro digital. and this is what i saw:

then I took it off

within minits it began to grow again

do you know what is that???

I have other problem too, my flame an multicolor angel are eating the base of same sps. Do the eat acros?

Mesenterial filaments...?

 

[fishieness]

Yes. Just mesodermal filaments. Nothing to worry about.

thank you guys only one thing left I treated my tank (first dosing) to kill red bugs but i noticed this 2 days later:

so I am blaming the angels 2 days ago these 2 last pics were not like this. and I am seeing the flama and the molticolor angel nipping on acros and also on top of montipora digitatas. so my question is: can a pest do this damage in 2 days? or its definitely the angels?

Angels will nip at the extended polyps. I don't think they will scrape the coral branches. I don't think red bugs have done that damage as well. You might have AEFW or just the corals aren't doing well. Afraid they are irreversible at this point.

I did a massive water change 50 to 60 %. can it be the cause?

I doubt it (assuming you have used water that is as close to the tank's parameters).
