Our take
Seapora's manufacturer catalog identifies item 59205 as a standard breeder aquarium with a listed capacity of 30 gallons and dimensions of 36 × 18 × 12 inches. The product appears in the catalog's Glass Aquariums section. Those details distinguish it from standard item 59203, which the same catalog lists at 36 × 12 × 16 inches, and support a glass breeder profile without adding a package claim. The frozen ASIN B01JS3A4DW is not linked to a current exact offer. Filter, lid, light, stand and model-specific construction details beyond the catalog entry remain unverified.
A shopper comparing a documented breeder-format glass tank who will confirm the 59205 label, dimensions and separately needed equipment..
Not for a buyer who requires a verified bundled setup, a 30-gallon standard-height footprint, itemized glass thickness or a current Amazon exact-ASIN match.

What the features mean for you
Identify the 59205 breeder model
The Seapora catalog gives this candidate item number 59205 and names it Standard Aquarium – Breeder – 30 gal. The catalog's section heading is Glass Aquariums, supporting a glass classification. The model number is useful because the same manufacturer lists several 30-gallon shapes and heights. The old Amazon title is a historical clue and does not prove which item code a current seller offers. Confirm 59205 on the product label or seller specification before using the catalog details to compare a listing; similar capacity language does not establish identical dimensions or a matching package.
Compare the 36 × 18 × 12-inch footprint
For item 59205, Seapora lists dimensions of 36 × 18 × 12 inches. That wider and shallower envelope helps distinguish the breeder format in a space comparison. It is not a support rating, filled-weight calculation or guarantee that a particular cabinet will fit. The source does not clarify the exact measurement convention or tell a buyer how much clearance to leave around equipment. Measure the exact unit and support surface before planning placement, and seek model-specific setup guidance where load requirements matter.
Keep capacity and water volume separate
The maker uses a 30-gallon nominal label for item 59205. That stated class is suitable for the finder’s broad ten-gallon minimum and falls below its fifty-gallon and seventy-gallon thresholds. It should not be presented as measured operating water volume: substrate, décor, fill level and equipment change the amount of water in a setup. The catalog gives no filled-volume figure. These are the only capacity conclusions carried into matching, so the product appears when capacity is flexible or the threshold is ten gallons and does not appear for larger hard minima.
Do not transfer package details from another Seapora tank
The source is an aquarium catalog entry, not a box checklist. It does not name a stand, lid, filter, pump, lighting, overflow or sump for item 59205. Other Seapora models may have different equipment or reef-ready labels, but those details cannot be carried to this breeder tank without a source for the same SKU. If the listing is sold with accessories, confirm the exact contents and item numbers. A bare-tank page and an aquarium kit are different buying decisions even when their gallons are similar.
Distinguish it from Seapora's standard 30-gallon tank
The same catalog lists Standard item 59203 at 36 × 12 × 16 inches and item 59205 as a 30-gallon breeder at 36 × 18 × 12 inches. Their shared gallon class does not make their footprints interchangeable. The breeder listing is wider front-to-back and lower in the catalog dimensions; item 59203 is narrower and taller. A shopper choosing between them should compare the exact model code and measured outside dimensions, then check support and package separately. This difference is more informative than a general 30-gallon title and does not make a claim about livestock or performance.
What else to compare
For a different Seapora standard 30-gallon shape, compare item 59203 at 36 × 12 × 16 inches. For a larger regular glass format, Aquarium Masters AM11120 is listed at approximately 120 gallons with 48.25 × 24.5 × 25.38-inch dimensions. The catalog facts distinguish those models but do not establish their seller packages or support compatibility.
