Note: this is a mystery project that I started 3.5 months ago, to raise one species of fish without knowing what they are. I’m affectionately calling them crocs for the time being. Once I finally figure it out I will update you all.
Since the start of this project, I have fed 24-hour baby brine shrimp to the fishes. There’s two reasons for this, especially in the the first 30-45 days. The live food needs to be small enough to fit into the mouths of the young fish. That became less critical after they were 60 to 90 days old. I could use 48-hour baby brine shrimp, because the fish had larger mouths, consuming them easily. The second reason for using live food is that it doesn’t pollute the water like dry foods would certainly do. The brine shrimp continue to swim about if they’re not all consumed in the first day.
Ten days ago, I added a breeder box inside the aquarium to hold the newly hatched baby “crocs.’ Tonight there appears to be 26, which I make sure to feed as well.
