1 Inch Of Fish Per Gallon Right?

[Jeff000]

Thats the general rule right, 1 inch of fish per US gallon?

I have whats in my sig, and wanted a 3 more guppies (2 female, 1 male), a 3 more Cardnals, 2 more serpea tetras, and then a male and female german ram.

I will be over the general rule, but the fish are at different levels in the tank, I'll them slowly and watch the levels, but should I be ok? Dont want to stress the fish or the ecosystem.

I have a canaster ehiem filter, and do a water change every 5-7 days.

That rule really only applies to guppies/tetras that will only grow to 2'', and tanks under about 15 gallons.

Try the community creator on ********* it takes into account how much mess is produced along with size and also highlights any personality clashes aswell. A great tool.

no to more guppies and rams, but yes to more tetras. the reasons are that rams and guppies are competitive and like to have space to call their own. tetras, on the other hand, like to have lots of their own kind around. and while watching pollution levels and doing extra maintenance will help keep your tank from self-destructing, there's no real benefit for the fish to cram in as many as can possibly be sustained in a single community.

as far as i know, the rule is:
"absent territorial needs, one can stock approximately 1" of fish per US gallon of slim-bodied fish under 5" in length without requiring extra filtration or cleaning beyond the absolute minimum"

i've never heard anything about only applying to 15g and under. if anything, a larger tank should really be stocked less heavily because the ratio of surface area to volume is less--meaning that there are fewer places for beneficial bacteria to colonize.

ignore the rule

The rule is a good general guideline. there are exeptions and i have also never heard anything about a tank under 15 gallons.

It's been said, but I think it's a very slight rule. I have a 29 gallon and have about 23 inches of fish and it's too overcrowded. It should be taken with a grain of salt, really.

^ That's why I'm saying only under 15g..

You're not going to put 18 2'' guppies in a 37 g tank are you?
