I just found a broken egg shell in the tank. My Female RES must've laid an egg and ate it. I felt terrible.
So how many eggs can she lay at once? I put her in a tub with some top soil. Do I need keep her at certain temperature? She seems to want to get out of tub. How long should I leave her in there?
This is the first time I've found egg in the tank. She didn't show any classical signs of being gravid. We recently upgraded to a 75 gallon tank for her and the other male RES because she escaped out the smaller tank we had. She hasn't been basking in the new tank as much as she used to. I don't think they've mated successfully. The male is much smaller in size and the female never showed any interest when he does the mating dance
So please help me. What should I do to keep her safe during this time? How do I know when she needs to be in the nesting box and she's done with laying eggs?
