...you are right - Rich never had to do too much becuase the fry could find lots of places to hide where other fish could not get to them.... he did have a box mesh I think that they could easily swim in and out of for the ones he could not catch and other would go into the raceways with the Xenia & pepermint shrimp.... in the wild, I have seen pics where schools of fry would hide in the spines of an urchine - you could even use an old brush or something similar.... just my 2 cents...
