I've had this guy for a week, and the other day i could see a brown slime/algae looking coat on his skin and fins. In the video you can see him dart off at the 1 minute mark and whatever is on his skin kind of peels off...then he comes back to eat it[emoji37] [emoji40] . Can anyone tell me what's going on? Tank is only 2.5 months old, and did just go through a mini cycle of what I've been told are dinos. Thanks for looking.
