So in the past two and a half weeks my frogs have released fertilized eggs four times. In the past six days, three times (every other day.) The first two times after frozen blood worms, third after a water change, and last after fed boring dry food in the hopes it would deter them (obviously no such luck.) On one of the off days, the male frog Timmy mounted the female Binga and held on for several hours. All Binga pretty much did was not move around too much. Binga is about 3-4 times the size of Timmy.
Is this amount of mating normal? What is causing it? Should I be worried about Binga getting hurt (they do mate properly), but she seemed really exhausted after the third one recently (not too interested in eating the frog eggs.)
The tank I have is relatively small 3 gallons for the two of them. They have a heater and a light. They have a big cave and a terra cotta pot. I have the original thing they came in which is 4"x4"x4". I am a student on a tight budget and the 150 dollars that I had to spend when I got them as a gift (with everything wrong) was a bit much already.
