I talked to a few people who have had them split and they all agree, I need to feed more often. I feed once a week, they feed every 3rd day so I will be following their lead. I really want this to work out to offer an alternative to wild caught stocks.
I have been talking to a diver down your way as well. He said he's seeing ritteris moving further and further south because of climate change. He said that 10 years ago they were VERY rare on the southern end of the GBR, but now they're showing up quite often, 2 at a time on quite a few reefs, green base ritteris too.
