I have had my Brazilian yellow-head since June 11th, 2011. I have always seen him eat FF(I dust with a multi one day and calcium+d3 the other) right as they were added to the tank. Then a week and a few days ago I added two springtail cultures to the tank (10 gallon) with one under moss in the front and one in the back under some mag leaves. Since doing this my frog does not go after any of the FF's I add right away and I havent really noticed him eating any of them at all. There are quite a few FF in the tank now, may 50+ free roaming. Is my frog going after springtails when I'm not around? He doesnt seem skinny but Ive also noticed that he tends to sit around in the shade of the Philodendron leaves on the cork bark a lot as opposed to roaming at times. I have caught him on the moss the past two days but other than that he just hides now. I also mounted 3 broms the day I added the springtails as well as some java moss. He seemed to love the java the day I added it. The frog is 3.5-4.5 months old. I'll post pics of the viv setup monday or tuesday.
