Hi guys , just bought 4 2-3" TFB recently . 2 red tail and 2 albinos . i have been feeding them hikari lionhead sinking pellets . got them 3 days ago , they started eating ytd . somehow their appetite is not as good as i expected and once the pellets hits the base of my aquarium(no gravel , bare bottom) , they will not go to get the pellets anymore . And what kind of food is good for power feeding TFBs? They are quite skinny and timid . If i get a few more , will it let them be braver and accept more food?
