Bioscape Fantasy Princess Castle 19 x 18cm
A grand fairytale fortress built for standard and larger tanks. The Bioscape Fantasy Princess Castle 19 x 18 cm is the larger of Bioscape's two castle ornaments, with multiple turrets and roomier internal chambers than the compact 12 x 8 cm version. Cast in non-toxic, aquarium-safe resin, it suits freshwater and marine display tanks with the floor space for a genuine centrepiece.
Key features
- Multi-turret castle design — larger mould with more battlements and archway detail than the 12 x 8 cm castle.
- Roomier internal chambers — bigger openings suit small to mid-sized fish rather than just fry.
- Non-toxic, aquarium-safe resin — cast for long-term submersion.
- Statement centrepiece — 19 x 18 cm footprint anchors a display or aquascape rather than sitting as a background piece.
- No assembly or gluing — positions directly on substrate.

Suitable for, and not suitable for
Suited to standard and larger freshwater and marine community tanks with at least 19 x 18 cm of clear floor space. Not designed as a dedicated breeding cave, and not marketed by Bioscape for terrarium or paludarium use. Check clearance around filter intakes and heaters before placing it, given its size.
Goes well with
Pairs with the Fantasy Princess Carriage w/Horse 21 x 12cm for a matched fairytale scene, or the smaller Fantasy Princess Castle 12 x 8cm if you want a second, understated feature elsewhere in the tank. A bed of fine, rounded gravel keeps it level and stops fish digging underneath.
Warranty and delivery
Covered by Bioscape's manufacturer warranty against defects, in addition to your rights under Australian Consumer Law. Ships as a standard parcel item; no special freight handling required at this size.
Common questions
How much tank space does this castle need?
Allow at least a 19 x 18 cm clear footprint, plus room around it so it doesn't crowd filter intakes or heaters.
Is it heavier than the smaller castle?
It's a larger resin casting than the 12 x 8 cm version, though Bioscape doesn't publish an exact weight for either size.
Is it safe for a marine tank?
Yes — it's listed by Bioscape as aquarium safe for both freshwater and marine use.
Do I need to rinse it before use?
Yes — rinse under running water to remove dust from moulding and packaging before placing it in the tank.
