My marinedepot shipment including brine shrimp eggs and loc-line arrives tomorrow, so I put together a quick DIY hatchery. It cost nothing and took about 10 minutes to make:
Cut up to 1L bottles, drill the cap and attach the hose. The hose even loops through a hole in the top to prevent backflow.
Tang update: I've been feeding every hour or so since I got home from work, just a tiny amount of minced plankton or frozen mysis. The tang eats his fill each time, and seems more active today. Dorsal fin is still frayed, as it was upon arrival, but is not getting worse. I'm usually against naming fish on the principle that they cannot be petted and are therefore not pets, but I have dubbed the blue tang "Chubs"
