Wasn't sure where to post this. Anyway I have had this BTA for over a year and this morning I noticed something on my BTA don't know if it damaged its self on a rock or if it's some kind of parasite/disease.I took a closeup of the area. PLEASE HELP.
It looks like a damage body, but it doesn't look that bad. Maintain a good water param for a few weeks and watch out if it moves around (may create more damage).
