Worried about my Acan

[richserpe]

Hello all

Had this black spot on my Acan for about 2 weeks. Can't blow it off with a syringe and it doesn't appear to be alive. Acan is puffy and healthy looking despite this spot. The Ironman above it is not affected. Any thoughts as to what this might be? TIA.

Looks like some piece of algae or detritus that the acan caught and is trying to eat. I would use tweezers and gently remove it.

U can also use a baster and give it a gentle swoosh.
