I was collecting some shrimp larvae last night, thinking that they were Lysmata amboinensis. However the adults were hiding and this morning I have noticed that they are both still carrying eggs. There was an additionally type of larvae also collected.
The shrimps/crabs that are in the tank are
Lysmata amboinensis (unlikely)
Lysmata vittata (unlikely)
Palaemon serenus / serrifer known locally as glass shrimp or boxer shrimp.
Hitch hiker black crabs of some sort (there are three or four in the tank)
Hitch hiker cream/white crab (I did find a fresh molt of one of these yesterday)
Hitch hiker pistol shrimp and possible mantis shrimp?
I think the majority of the fry collected are Lysmata vittata
Then there are the odd ones that I would like to identify
These fry are about 3-4mm long and they are attracted to light (but less than the Lysmata vittata) and will "hang" from the water surface with their heads down.
They are very quick swimmers and until I looked at them with the camera, I was thinking that they were a fish larvae/prolarvae from their swimming motion.
Any suggestions would be great.
