I had an unplanned breeding (male got out of his holding cell inside my tank). My two crowntail have bred and the fry are about 4 days old now. When I saw them in the bubble nest, there must have been hundreds. First off, like I had said, it was unplanned, so I have gravel at the bottom of the tank, 5 ghost shrimp that wont be caught and a sponge filter inside the tank. I've already removed the parents. I turned on the sponge filter on day 3 after the fry became free swimming, but after that, I can only see about 20 fry left. I cant tell if there are fry at the bottom and if there are, what are the chances that they've been eaten by the shrimp? As for the surviving, they only stay at the surface of the water. I've been doing my research and trying to find information so that I can keep these babies alive. When I looked up what the free swimming fry should look like, the videos depict them all over the tank, not just at the top. I'm worried. I've assembled my hatchery for the brine shrimp and for the past 2 days have been putting them in the tank. I havn't seen the fry eat at all but the shrimp eventually clear up. I'm wondering if the fry are eating, if the BBS just fall to the bottom and get eaten by the shrimp, or if they're just being caught in the filter. Ugh... I didn't want to breed because I didn't want to deal with all of this but here I am. Now I just want to do right by the fry.
Please help me.
