I recently started feeding my axolotl more frequently (every other day) with a greater quantity as well as a greater variety (earthworms and pellets) of food. He was also moved from a 25 gallon tank to a 40 gallon with better filtration. My question is: Would the above have anything to do with his gills getting longer and more "bushy." I looked at some older pictures of him and his gills have definitely grown. I did not know if that is usual or even a good thing because I get the impression this means he needs more surface area on his gills to pull more oxygen from the water. Maybe I am stupid...any input would be excellent.
THANKS!
