OK, please take this thread in the spirit intended. I am not trying to "bend any rules", or "reinvent any wheel", I am just curious and interested about the concept of fish stocking. I have seen capacity quoted in many different ways, 1
inch per gallon, or based on surface area, or even a volumentric calculation. I realise that on average these probably all equate to the same thing, though obviously for example an odd shape (as I have) or extreme examples break any rules. A 10" fish in a 10 gallon hex, probably not happy!!!!! 10 1" fish in there, probably happier!
I have a Biube from reef one like this one

The specs have it as a 13" diameter cylinder, height 18 inches. With the subtrate and bubble tube and items, you basically get about 30L rather than the 39L quoted capacity.
I also realise that you can imagine this tank as two 13" diamater cylinders of 9" on top of each other, since fish tend to swim horizontally, so I totally understand why a 10g rectangle is better suited to some fish than a tall one.
When I use the stocking calculators online, e.g. aqadvisor.com, it basically says that
2 guppy & 2 platy = 100% stock, if I plug in a 10g hex and adjust the distances as 13 inch wide and deep, 18 inch high.
Also at 100% stock is 10
neon tetra, which since I know can reach 1.5", potentially breaks the 1 inch per gallon rule, however, I know neons are very thin, so I can imagine that this is why the calculator says 10 is OK.
All along I have had in mind, a pair of guppy, a pair of platy (all males to avoid fry probs, and they are smaller than females), and THEN have a small group of neons. The aqadvisor calculator is super sensitive to the values definining the surface area of the tank and I am not totally sure how to best equate a cylinder to a hex.
I think I will now decide between the two pairs of guppy/platy, with an amano shrimp in the bottom
OR
a group of neons. 1" per gallon would say 7 neons is full, so why the discrepancy with aqadvisor.com, is it the slimness of the fish.
Also, since the water volume is closer to 30L, that is actually only 8 US gallons, not 10, so maybe 6 neons would be OK in there. However, remembering when we had 2 guppies and 3 neons in before rehoming them prior to cycling the tank properly!, it looked pretty empty, I cannot imagine 6 neons "filling" that space
What do you think?
(as an aside, does anyone know how platys and guppies - male - fare when on their own, eg in a 1 guppy, 1 platy, 5 neon tank)
Just an update:
adjusting the "width and depth" of the tank to get the 9g capacity, it says the tank is only big enough for 3 neons. I just cannot believe that can be the case!
OK, for reference!
Assuming a "real" volume of water of 9g US, and with a radius of 6.5", the way to get aqadvisor to match is to set
length = depth = 12 inch, height = 14 inch.
This gives a stocking calculation of
100% = 6 neons (sounds more reasonable than 3!)
90% = just 2 platys OR just 2 guppies, OR 1 of each
Still interested to hear comments on this, but basically sounds like I am now down to a mini school of 6 neons, or a platy pair, or guppy pair
At a push, 3 platy or 3 guppy is 109%, "to me" it sounds like 109% would be fine, I am planting with several real plants and will be very active with maintenance. As to which combo will be more fun to look at and look after, well, what do you lot think?
