Cholla wood turning color

Good afternoon everyone!

I have a 55 gallon tank with a few pieces of cholla wood for my shrimp and one of the pieces is starting to turn red. I did some research online and haven’t been able to find any answers. I had the “slimey goo” that I’m sure some of you have experienced but this is new. Just checking in to see if anyone may know the cause and if it might be something that may possibly be harmful.

I am not sure as to what causes it to turn different shades of purple or red. But I have some large teddy bear cholla pieces, they've been in my 20g for Two years, and they did this. Had purple spots on them. After about 6 months it went away. After 1 year the entire piece turned a dark brown. So maybe it just does it when new? As far as I know it poses no harm or danger to your water pets.

Thank you very much for your response kathylee

 

The purple color change is harmless and common phenomenon in aquarium woods. That gooey stuff is biofilm and your shrimp will love it!

Thanks yeti. Yea I have seen the biofilm several times and I just rode it out til it went away. The change in color was a new experience so it concerned me.
