In the screenshot of the profile in my first post, SF gives the footprint of the minimum size the fish should be kept in as 90 x 30 cm; it does not mention the height. The orange box uses the volume 81 litres and this canbe misinterpreted as SF saying this fish needs a tank of 81 litres volume but SF says no such thing. The volume in the orange box makes the assumption that a tank with the footprint given by SF is only 30 cm tall while many 90 cm tanks are taller than 30 cm.
For those of you who don't use metric, SF's minimum footprint is 36 x 12 inches; the ad's volume is 21.4 gallons, and a tank with SF's footprint could only be 12 inches tall to get that volume.
I used to have a tank with half as much volume again as the tank size in the ad (125 litres or 33 gallons) but it was only 80 cm/31.5 inches long. This tank was not long enough for the species in the profile but the ad implies it was more than big enough for the fish. It is in fact just an ad for a filter for an 81 litre tank, not the volume of a tank needed by the species in this profile.
Yes, a lot of the ads do contain the correct information, but some don't. This is why we need to look only at the information in SF's own text so we don't get caught out.
