Hi Quixotic,
Sorry for a very late reply.
1. I don't feed them with any artificial food.. Only brown algae that I grow in my tank..
2. When they're hungry, they'll hunt for the algae
3. My tank 24 hrs give them the best food
4. I have 10 of each species, celebes beauty, brown camo, red goldflake (yellow cheek), and dark maroon.. But, some of them already gone to heaven..
Only about 3 - 6 for each species left because my longtime experiment to find their optimum living condition...
But, here's my latest update...
Yellow cheek carrying her eggs..
Brown camo carrying her eggs..
Celebes beauty shrimplet... Sorry can't get a better picture.. My camera not good enough for macro shot..
I still waiting for the dark maroon to carry eggs soon.. Maybe, they're still not mature enough to breed...
