ANS Isolation Box 10x10x10cm (Single) for SG Tanks

This compact 10cm single-chamber box is the in-tank refuge we suggest for small jobs: separating a single berried shrimp, a nipped fish recovering from a squabble, or a betta you need to keep apart for a day or two. Because it hangs inside your main tank, the occupant shares your established, heated water rather than sitting in a cold, uncycled bucket, which is exactly the gentle, low-stress isolation a stressed fish needs while it settles.

At only 10cm it is best for genuinely small or short-term occupants, and for Singapore keepers it is a tidy way to manage a community tank without finding floor space for a second setup in a flat where every corner counts. We recommend siting it near gentle flow so fresh water exchanges through the slots, and keeping a close eye on jumpers since these open-top boxes offer no lid. Drip-acclimate any new arrival before moving it across.
