How many fish is "too many"?

[h2oengr]

Is there some sort of rule for how many compatible fish you can have in your tank? I've heard like 1" of fish per 10 gallons of water - that sounds way too scarce. Thanks.

1" every 5 gallons is what i use. Take the adult size of the fish when using that tho.

1" for every 3 gallons or 1" for every 5 gallons is what most people use. I reccommend using the 1" per 5 gallon rule.

yeap 1" per 3 gallons,its more of keeping the water quality good then size unless you have a smaller tank and aggresive fish.If you have a community tank then the addition of a skimmer or fuge or sump will increase the capacity so I have heard Just my .02 cents

depends on the fish. Some school some are territorial. But I would go 1" per 10g for adult fish. Why? 1" x8" fish ......a 8" fish wouldn't have much room in a 2 foot tank? 24g. But in the same token I would think you could have a 6" fish and 4-5 smaller ones in a 90g. Point is there is no rule just don't pack large fish in any small tank . I like to keep one main fish= large and rest small. Seems the large/med fish keep all the small ones from killing eachother. When I had just small fish they would fight all the time but not when theres mixed sizes. JME
