The RQ2318 Castle Decoration as a Tank Centrepiece
A castle is the classic crowd-pleaser, and this RQ2318 piece works because it is both a focal point and a genuine refuge. At 14x11x23cm it stands tall enough to anchor a mid-sized tank, and the multiple openings and passages give fish real shelter to swim through and hide in. That matters in a community tank: secure fish are confident fish, and a structure with several entry points spreads out territory so squabbles ease off.
Rinse it well under running water before adding it, and never use soap. The resin is inert and aquarium-safe, so it will not affect your soft, slightly acidic Singapore tap water or pose harm in freshwater or marine setups. Because this is a taller piece, we suggest setting it toward the back or a back corner so it frames the scene without blocking the open front swimming zone, and a couple of plants alongside help it feel rooted in the layout.
