ANS Isolation Box 20x10x10cm (Double) for SG Breeders

The double-chamber 20x10x10cm box is the one we recommend when you need to separate two occupants at once while keeping them in the same shared, heated water. The divider lets you hold a pair of sparring fish apart, condition a male and female on either side ahead of spawning, or grow out two small batches without buying two boxes. It hangs inside your display, so both chambers stay at your tank’s stable temperature and you can watch each side easily.

For Singapore fishkeepers working in tight HDB or condo spaces, fitting two isolation jobs into one in-tank unit is a genuine space saver, and running both on your established filtration avoids the risk of a separate uncycled tub. We suggest positioning it where flow refreshes both chambers through the slotted sides, feeding each compartment lightly so leftovers do not foul the small volume, and minding the open top with active jumpers.
