Aqueon and Marineland/Perfecto both skip a nominal 100-gallon tank, jumping straight from 90 gallons to 120.
A sortable reference covering 70 aquarium models from 8 manufacturers, 2.5 to 300 gallons, listing outside dimensions, glass spec, and dry and filled weight.

Aqueon and Marineland/Perfecto, the two biggest US glass-tank makers, both skip straight from 90 gallons to 120 — neither sells a nominal 100-gallon rectangular tank. The 100-gallon size only exists as acrylic, built by three makers who don’t agree on a footprint: TRUVU’s 48x24x20 and 60x18x20, and Pro Clear’s 72x18x20. At 75 gallons, Aqueon and Marineland/Perfecto use nearly identical footprints but their filled weights differ by 88 lb.

The Full Comparison Table
Reported Length By Nominal Gallon Size
Each dot is one manufacturer's published outside length for a nominal gallon size, all 70 rows plotted. Rows with one tight cluster of dots mean sources agree; rows where dots spread wide mean they don't — the 75- and 100-gallon rows have the widest spread in the dataset, with three disagreeing 100-gallon footprints alone.

Method
12 distinct WebSearch queries covering Aqueon, Marineland/Perfecto, TRUVU, Waterbox, Custom Aquariums, and SC Aquariums, followed by sequential WebFetch verification of every URL used. marineland.com PDFs failed WebFetch with a TLS certificate error, so they were downloaded with curl and read directly as PDF files (page 1-2 read via the Read tool, contents transcribed in this JSON). truvuaquariums.com, customaquariums.com, and empire-usa.com returned HTTP 403/429 on direct WebFetch; all three were re-fetched successfully through the r.jina.ai reader proxy and are flagged as such in their source notes. Two candidate sources were fetched but discarded per the no-fabrication rule: an Amazon listing for an 'SC Aquariums 100 Gallon-B' tank returned HTTP 500 on both direct WebFetch and the r.jina.ai proxy and could not be verified, so no 100-gallon SC Aquariums row was added; a direct scaquariums.com/empire-usa.com URL for the same 100-gallon PNP model 404'd.
Gaps
Numeric glass thickness is not published by Aqueon or Marineland/Perfecto for their standard rectangular line (only a tempered-bottom Yes/No flag) — we couldn't find one, so those cells read '—' rather than a guessed value. Empty/filled weights are not published by TRUVU, Custom Aquariums (75/100/300 gal), or SC Aquariums (75 gal) — we couldn't find those either. The SC Aquariums 100-gallon-B (48x24x20, 12mm) figure appears in search snippets and an Amazon listing title but the listing itself 500-errored on every fetch attempt, so it was left out entirely rather than trusted unverified. Waterbox Aquariums was searched and its technical-specifications page was fetched, but Waterbox sells metric AIO/reef-cube model numbers (e.g. 'AIO 65.4', 'EDEN X 105.4') rather than the standard nominal-US-gallon ladder this table tracks, so no Waterbox rows could be mapped in without guessing an equivalence — omitted rather than forced.
