i know im a bad mom for having f=gravel in the tank, but this frog is like 10 years old (i got her 8 months ago) and has always had gravel in the tank. she has a noticeable lump on her stomach. i put my hand in the tank to see if it was gravel or eggs ( she gets fat and lays them on ocasion) its deffinately gravel. is there anything i can do? she is a very large acf about the same size as my hand. any advice would be very helpful. thank you
