If you can put that into gallons I can help you so per inch of fish you'll need 1-2 gallons
 
75 UK gallons or 90 USA gallons

Hello nat...

An 85 gallon tank is nicely sized and if you stock the standard medium sized adult fish available at the local pet store, then you can easily have 60 such fish. You will need to follow a sound tank maintenance routine to ensure the health of the fish and plant the tank well to maintain stable water conditions.

I keep large tanks and like Danios, Platys and Corydoras.

Inch per gallon is very outdated and completely inaccurate way to stock a tank.

The following need to be considered when planning stock.

- Foot print of the tank
- Adult size of the fish, not the size they are when you buy them.
- Bio-load
- Aggression levels of the selected species.
- How much filtration you have/will get
- How much time you can dedicate to water changes.
- What decor will be used and how much swim space it will take up/how much water it will displace.

For general community fish I find aqadvisor.com to be a better solution than the 1" per gallon rule. It is not perfect by any means but a lot better than nothing.
