I have just noticed my small angels nipping at some of my plants. is this a normal behavior? maybe they are hungry... does anyone else have this problem?
my water is in great quality. they are juveniles ive had for about a week now. thanks!!
they must be young... they are about an inch or two long, and three inches tall.
Okay well definitely not mating then (side note: as far as angels go most people determine age not by length or height but by body size as compared to a coin (dime, nickel, quarter, half dollar). Likely they are just eating the biofilm off of your plant
I just donated 3 half dollar sized Koi Angels to my LFS because they nipped on my bacopa, hygrophila, HC and other plants. All new growth quickly became a snack for them. Their diet was just fine and not lacking any nutrients. They just enjoyed chewing the heck out of my plants. So yes, it is very well documented that some angels will eat and bite on plants.
