Pineapple Hideaway Aquarium Ornament
Two portholes and an open base to swim through.
Two portholes and an open base mean there is no dead end inside. A fish can enter one way and leave another, which is the difference between a retreat and a trap.
Taxes calculated at checkout
- Arched base opening fish can swim through
- Two round side portholes for light and cover
- Hand-painted resin that keeps its colour
- 13 cm tall, suits a small or mid-size tank
- Sits stable on gravel or sand
Why you'll love it
Made for happy, healthy pets
A hide that is actually open
Plenty of novelty ornaments mould the openings shut and sell the look alone. This one is hollow with a clear route through, so it earns its footprint as cover rather than clutter.
Colour where a planted tank has none
Live planting settles into greens and browns within a season. One warm-toned piece gives the eye somewhere to land, which is why bright ornaments outsell naturalistic ones by a distance.
Resin holds up to water changes
Painted plaster chalks and clouds. Sealed resin comes through years of siphoning with its colour intact and without nudging the water chemistry.
Good fit if
- Small community tanks needing a usable hiding place
- Bottom dwellers that spend the day under something
- Children's tanks, where the recognisable shape is the appeal
- Nano setups where one ornament has to do everything
Look elsewhere if
- You want a naturalistic scape
- Your fish are too large to pass through the openings
- You need something that disappears visually
Why two openings matter
A cave with one entrance is a dead end, and cautious fish treat it accordingly. Anything that can be cornered inside will hesitate at the mouth and often decline to go in at all, which means the shelter you provided is not doing the job you bought it for.
Two portholes plus an open base gives multiple routes in and out. A fish can leave whichever way something is not approaching, and that makes it a space they will actually use rather than inspect. In a tank with more than one territorial fish it matters more still.
Sizing the openings to your fish
The risk with any ornament containing holes is a fish that fits in and cannot get out, or one that wedges part way. Measure the widest fish in the tank against the openings, and remember that a fish still growing will be a different size in six months to the one you assessed today.
The rule is that an opening should be either clearly too small to enter or comfortably larger than the fish. The dangerous middle ground is a hole a determined fish can push into, which usually happens at night when nobody is watching. Reassess every time you add a new species.
Placing it well
Put it in the mid-ground rather than against the back glass. Being able to see into the openings means you will notice a fish that has taken up residence and stopped coming out, which is often the first sign that something is wrong.
Bed the base into the substrate so it sits firmly and cannot be tipped. If you have several small fish, a second retreat elsewhere in the tank is worth adding, since one shelter in a community tank becomes something to compete over rather than something everyone benefits from.
Keep it out of the direct filter outflow. Fish use a retreat to rest, and a shelter with a current running through it is one they will use far less than a still one. Somewhere sheltered by planting on at least one side works better than open floor.

Good questions
Before you buy
Yes. The arched base opening is the one a betta will use; the round side portholes are narrower and suit smaller fish or shrimp passing through.
It is sealed resin rather than surface-painted plaster, so it survives water changes and gravel vacuuming. Scrubbing it with anything abrasive will still take the finish off.
No, it sits at about 135 g and stays put on gravel or sand. Press the base in slightly rather than balancing it on top of a deep substrate.
Bottom dwellers and shy species usually take to it quickly, especially with two exits. Fish that prefer open water may ignore it, and that is fine: having the option available still lowers stress.
Check the openings and seams with a stocking drawn over them first. Anywhere it snags is somewhere long fins will tear, and a betta uses a retreat repeatedly through the day.
Scrub it in a bucket of water taken from the tank during a water change. Never soap, and rinse new ornaments under warm running water before first use.
