Today, I actually took time off from work to visit Justin at Ocean Aquarium. He built me a small fry trap out of an old Rubbermaid container. On each of the short vertical sides, he'd cut out a large circle. Over each of these holes, he'd epoxied the finest netting, fine enough to prevent fry from swimming into the main tank, large enough for aeration from the main tank to occur unimpeded.

I also bought frozen baby brine shrimp, which I'll feed the fry once they're a little bigger. Now, at only about 2 millimeters, they will feast on infusoria. Today, I put about 4 drops of infusoria right into the trap. Trace elements of it will leak into the main tank, which is fine. Apparently, I need to do this 2 or 3 times a day.

The Neon tetras are frustrated that they can't get to the fry through the trap walls. The two fry I left behind in the main tank are already gone, either eaten or sucked into the filter.

Two of the 9 fry in isolation are rather intrepid, striking out on their own to explore the rather large trap (about 1.5 gallons). The others huddle in a corner.

I think I've seen one of the fry dart enthusiastically in search of food. That's a good sign.

I'm very excited about this, although I haven't yet given any thought to what to do when these fish get bigger. I may divest the 10g of its tetras and devote the tank to cichlids. We'll see.
