I have a 29 gallon tank with 4 Jewels. 2 of them paired up and just laid eggs yesterday. One is trying to dig a hole to put the fry in, but I only have 1/4" of gravel. There are 2 flower pots and a small cave. Could I add more gravel, or would it be best to leave them alone? I put them in here a week ago as a temp tank.
