  • We are currently upgrading MFK. thanks! -neo

i see the holes. do u know if the holes was there before? idk if this is hole in the head or bite marks from a fight maybe or maybe they are just normal none of my polys have them so this is weird.

i dun know i never actually check it until today i brought it like 3 months ago
 
its fine what you're seeing is part of the laterline -Anne
 
they kinda look like bit marks but they are to far apart. maybe it already had them just get them on some type of pellets and keep the tank clean and if it goes away cool lol!!!!
 
LATERAL LINE
The lateral line system consists of bendable nerve endings in a series of mucous-filled canals Vibrations in the water or differential pressure in different parts of the canal cause the fluid to move and distort the nerve endings.
Because of it's name, we think of the lateral-line system as being oriented laterally on
the fish.Closer inspection shows a concentration of sensory receptors on the head
branching into 4 lines.The occipital,The supraorbital, The suborbital and The
hyomandibular.
The lateral line system enables detection of both vibrations in the water and changes in the pressure field set up as the fish swims. It provides information to the fish about movements of nearby organisms, very-low-frequency sound, differential current velocity, and back pressure built up as the fish approaches an obstacle.The lateral line sense is sufficiently directional to enable blinded fish to find and capture prey.
A swimming fish sets up a pressure wave in the water that is detectable by the lateral line systems of other fishes. It also sets up a bow wave in front of itself, the pressure of which is higher than that of the wave flow along its sides. These near-field differences are registered by its own lateral line system. As the fish approaches an object, such as a rock or the glass wall of an aquarium, the pressure waves around its body are distorted, and these changes are quickly detected by the lateral line system, enabling the fish to swerve or to take other suitable action. Because sound waves are waves of pressure, the lateral line system is also able to detect very low-frequency sounds of 100 Hz or less.

so the hole on the head is normal ?..anyway thank for the info:)
 
Phew... I was worried! Glad it is something normal. :)

check your water params and fix immediately, raise the temp a couple degrees, and make sure you're providing proper nutrition. Most of the time with polys, it's because they're not getting a varied enough diet.

boy don't I feel silly... polys do like a varied diet though so at least I was right on one thing! lol
