how accuarte is aqadvisor? - 7 geos in 40gal

[mattybecks]

As the title suggests I was wondering what fellow members who are familiar with aqadvisor.com think of the accuracy of this stocking calculator. I always thought it seemed quite good, and I like to play around with it.
Recently it said that my 7 x geophagus Tapajos (adults) would be ok in a 40 gal tank (122% stocking, still in the green, usually I go max at 120% as I do over filter) with no mention of fish getting to big size wise. When I removed one it said 6 was 108%.
Do you really think 7 or 6 x geos would be ok in a 40gal? (1m, 35cm width in length)

Currently my geos are in a 130gal 6ft tank - not planning on moving them.

Although the Tapajos are generally smaller, and a 40 might be OK as a grow out tank when they are juvies for a couple months, I wouldn't keep 7 in anything smaller than a 6 ft tank.
For the ones I had, a 125 gal worked well.

Honestly I don't like AQadvisor. What do they mean by overstocked? Their water change schedule is a bit unusual as well. Might just be me.

I thought maybe it was just me too. Which is why I wanted to get some other opinions.

aqadvisor consistently gives bad advice imo. Seems to follow some generalised matrix for fish size and water volume, without accounting for the behavior or activity level of the fish.

The rule (the rule hold myself to) for any cichlid and tank size, is 10 gallons, per inch of adult.
This means I take estimated length, height, and width of an adult and add them up.
So for a 40 gallon tank my combined max size cichlid estimate is 4 inches or less, and is the size that will fit in that size tank.
The combined L-W-and H of most all kept adult red head Tapajos is about 7" L, 2-3" H, and a body width of almost an inch.
This to me means a tank of around 125 gallons, minimum for 7 healthy adults.
The "Tapajos" below is half grown, at about 4"L, 2" tall, and a little less than 1 wide, so already needs (to me) a minimum 75 gal tank as a temporary grow out.

Thanks. This makes sense
