Frequently asked questions
How much is LEGO Fish Tank (31122-1) worth?
LEGO Fish Tank is worth approximately $95 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO Fish Tank retired?
Yes — Fish Tank (31122-1) has been retired by LEGO and is no longer in production. Retired sets have fixed supply, which is why their prices are driven purely by the resale market.
Has LEGO Fish Tank gone up in value?
Yes. Fish Tank launched at $30 and now trades around $95, an increase of 216.8%. See the price history chart for how it got there.
What is the price per piece for Fish Tank?
At its $30 retail price across 352 pieces, Fish Tank works out to about $0.085 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Fish Tank a good investment?
Fish Tank currently trades 216.8% above its $30 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO Fish Tank so expensive?
Fish Tank was released in 2021 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
