I know that convicts spawn as easy as male + female + water = babies and I know that they tend to lay eggs in pits dug in the sand if a cave is not provided. My female convict has begun to dig a little pit. Should I be expecting a spawn?
Not really. She is staking out her claim to attract a mate. They will lay eggs anywhere, even stuck to the glass. Just means she's getting ready, now it's up to a male.
