What is the ratio for fish per gallon2007-11-24 23:41:52

I heard that it was 1 fish per gallon but my tank is 55gals. I know i can't put 55 fish in there. I do have about 22.

Answers:

the general rule is 1 inch per gallon. although this can be bent a little depending on surface area and amount of filtration.

1-2 per gallon

Better get some more so the ones you have won't be lonely

---

1 gallon per inch of fish

so 55 gals can hold 55 one inch fish. chances are as long as your fish aren't too ungodly big you're ok.

I was told 1 inch per gallon, but I would go with less unless you want to be changing your filter every other day.

---

22 is enough. unless they are neon tetras.

---

it really depends on the size of each fish. if your 22 is not crowded, you're okay. go to a fish shop and compare their 55 and your 55 filled with similar numbers of fish. good luck.

in 55 gals, i think you can have 30 fishes and above if your fishes are guppies type (small fishes) ..

although theorigically says 1 inch fish per gal, but its really depends on how you mentain ur tank.. if you prefer to have more fishes, then just go for it.

Keep water change and clean filter weekly will helps your fishes grow healthier and happier.. control well in their diet ..

There is no rule when determining how many fish to put in a fish tank. The one inch per gallon rule is just for small stream lined fish but 55 in a tank is way too much. about the twenty you have know should be good if they are small growing only. If you want goldfish I would suggest only three or four. Oscars only two at best. Pacus one. The rule changes for each type of fish you have. What are the fish you have right now? Maybe the tank is over crowed as if.

It depends on the type of fish and how big they get I think the ratio is 1 gallon per inch of fish. so if u have 1 fish that is 20 inches and another fish that is 25 inches then I would say only 2.But if u have 55 - 1 inch fish I would say that is enough. Just remember that most fish u get at pet stores are young and will grow. The best place to ask about fish is like petco.

1 inch per fish per gallon but take in to consideration adult size and go ahead and figure that in now

That 1 inch of fish per gallon rule is not right. Think about it this way. 12 inches of an oscar does not equal 12 inches of neon tetras. The oscar is way thicker and messier than 12 neon tetras. Not only that, it depends on how aggressive your fish are. Aggressive fish need more space.

Here's a list of possiblities since you didn't include a stocking list.

22 tetras, rasboras, danio, cory cats, etc are fine (and probably even a little under stocked)

22 African cichlids- over stocked (over filtration will help but they may kill one another to get territory)

22 large Neo-tropical cichlids- WAY over stocked

22 dwarf Neo-tropical cichlids might be okay but may be too many.

i inch per gallon

It completely depends on how big each individual fish get.I've heard the crazy fact of one fish per two gallons.But ask your local fish store.Good luck!
