Ok I found two white tubes right below my acro that came on the same piece of rock as the acro. I'm unsure on how to post pics straight to the form so I put them in my profile under my 55 gallon in wall build. I posted three pics and theres more info on the first pic of the problem. Please check it out and let me know if this is going to become a major problem or not. Or maybe its not them and its happen due to poor care. It's my first acro ever so its possible. I do have a few other sps and they are all looking great and growing. Thanks
