These little guys are powerful! So far, they've spent their days battling a very strong current (2 AC110s on their end), and ripping algae off the back wall. If these guys don't grow up pure muscle, I'll be amazed. I'm thinking tonight or tomorrow I'll be moving them to their own seperate 20g long to grow-out. I'll be doing daily 50% water changes on the fry tank, with 5 or 6 small feedings through the day of Daphnia and baby brine shrimp for optimal growth. I'm thinking of putting 2 AC110s on the 20 long also, for as much current as possible (the filter intakes will be wrapped in a filter bag so they don't get sucked in) to see if they build alot of muscle swimming against it all day.
