Moving fry is the delicate step. Scoop them with the 2-inch Shrimp Net, whose soft nylon pocket is 2 in deep, and release them into the Acrylic Fish Breeding Box. It comes in Small, Medium, Large and a size for tanks up to 40 gallons. Inside, the Small box measures 4.2 by 2.7 by 2.8 in, and its slotted floor lets waste drop out while the fry stay put.

First food and clean water come next. The Brine Shrimp Net Kit holds back eggshells in its 80-mesh net and collects the newly hatched shrimp in the 200-mesh one, then hands them out by pipette from 5 storage tubes. Once the fry move to a grow-out tank, a Mini or Nano Bio Sponge Filter moves the water without pulling them in.

All 8 picks for breeding boxes and fry care come from Pawfly aquarium supplies.

Questions about Pawfly fish breeding box

Which Pawfly breeding box size do you need?

Go by the size of the fish and of the tank. The Small box, 4.2 by 2.7 by 2.8 in inside, is for tiny fish or shrimp only. Medium and Large give more room, and the largest option is made for tanks up to 40 gallons. All four float or hold to the glass.

Which Pawfly automatic feeder covers your trip?

For a long trip, the battery feeder: with its extension it holds 450 mL, 1 to 2 months of food, and 3 AA cells run it for 4 to 6 months. Shorter absences suit the rechargeable 320 mL feeder, which lasts 3 to 6 months per USB-C charge. Test the portion size before you leave.

How does a Pawfly breeding box keep fry from slipping out?

Through its floor, a slotted panel. The slots are slim enough to hold newborn fish in while debris, leftover food and waste fall through to the main tank. Clear acrylic all round lets you count the fry without lifting the box out.
