After starting my shrimp bowl(2g) a couple months ago, I am finally, within the last week, seeing baby shrimp. I started with six RCS, 4F and 2M, and all of the females were impregnated. A week ago, the first ones hatched, and within the last day, the second batch has come into being. There are still two berried females, so I'll be seeing a lot more shrimp very soon. I am worried about overpopulation though, as I've gone from six adults only to adding +/- 30 shrimp in varying stages of the life cycle quite quickly, and I'm soon to have at least 30 more. I have a 10g that has been cycling for a while in anticipation of a clutch of apple snail eggs that seem more and more likely to not be fertilized, so I'm thinking I will throw them out and give a new home to the shrimp. Filters(1 HOB and 2 sponge) should be full of bacteria, but the tank is just a bunch of gravel right now because I didn't feel a need to spruce it up for a bunch of baby snails. Would putting in a soil substrate with a sand/gravel cap right now be a bad idea, or should it be fine with cycled filters running? I will need to move in the next couple weeks, so I'm not sure about my best course of action...
