Hey all… hoping I post to the right forum, still new to the hobby/R2R (about 6 months). Have had this monti for about a month now. just added some fish into my display tank about 2 weeks ago after quarantine. Today I did a water change… and noticed this for the first time. what the heck is this white stringy stuff? Any ID/help would be much appreciated! Thank you!!
