I still have 10 opeaula in my habitat and they they all look healthy and it looks like they are all eating. I can tell they are healthy because they are swimming around. Now there is finally algae in my habitat. I have been trying to feed them once a day but once in a while I forget. My shrimp are all red but not super red. My opeaula get sun light from behind a thin curtain. I do not have any eggs yet but i am sure I will have soon.
