hi everybodies, so i finally have the time to raise my fish and here goes.
my larval tank is about 3liters, it’s a black bucket with a bubbler

so i’m raising neon gobies here’s a time line

-fish hatches
-i do a minor water change
-i buy more rotifers for backup and put them into the tank
- i add in saltwater infusoria that i raised
-i top up the phyto
-i leave the house for 2 hrs
- some idiots appear and cover the surface
-i can’t find the larvae

they look like rotifers when not zoom-ed in and they look like triops when i look closer. my infusoria has none of these that i can find
i pray that my larvae are still there

i just checked, there’s like 10 larvae dead on the surface
