Arrow How many?

I'm setting up a 55 gallon and wanted to know how fish I can keep without overstocking.

Here's what I plan to keep: six xray tetras, three marbled mollies, three albino koi swordtails, three platies, 1 pearl gourmai, and four peppered cories.

Is this too much, a good number, or can add more?

I'd suggest trying AqAdvisor - Intelligent Freshwater Tropical Fish Aquarium Stocking Calculator and Aquarium Tank/Filter Advisor
It's a good fish stocking calculator, but remember it's just a general guideline and you need to crank in some common sense. I'm assuming with 2,000+ posts, you know more about this than I do!

I think that is good if your filtration is adequate.

I would mention that the gourami might not appreciate the faster fish though, but none of the fish you listed is overly speedy, except sometimes the mollies and tetra can be. Also I would note that the swordtails and platies can crossbread (might be your purpose as you have them as 3 each). Also, I would probably up the amount of cories to around 6 as they are happiest at that number, and peppered cories only get to about 2 inches.

The previous poster's suggestion of aqadvisor.com is right on...plug in the tank size, filters, and the stock you want and it will let you know what's up as far as filtration needs and if you are overstocked or what not.

Good Luck...and let us know what aqadvisor says...as that amount of fish doesnt sound that major of a bioload in a 55 gallon if the filtration is good. Most advice filtration for the next tank size up of what you actually are stocking. And plants always help! (I have a 50g and 30g filter on my 29 gal. And I have a 20 gal and 10 gal filter on my 15 gal. When my 5 gal is up I have a 10 gal filter on it.)

I think you still have lots of room for more fish. It mainly comes down to what you think though. As long as fish are compatible and do not outgrow a tank there is a lot of opinion in stocking.

It says that with the fish I have and filter a Marineland penguin 350B( goes up to 70 gallons) that I need another filter. When plugged in the Marineland emperor 400( which goes up to 80 gallons) it said that was a fine amount of filtration. Why did it say that? Whats wrong with the penguin?

When it comes to Marineland filters, penguins seem to be widely known to have a lower filtration level...however I hear once you go to the emperor filters they are much better.

I have a penguin on my larger tank, I hated it, I kept it on and added an AquaClear 50 to work with it. (So I have like 80 gals worth of filtration on my 29 gal tank).

Also, on aqadvisor, they only use something like 65% (?) of that particular brand of filter's power and specs to give room for any inconsistancies with the manufactures' specs on their filters.

On aqadvisor, when I plugged in what I wanted in my new 15 gal it said I needed more filtrations (and it has 30 gal worth on it now) but it only had me at 94% stocked...so I think they might be giving a lot less credit to filters than they could. Not to mention, they dont account for any live plants. And they have no way to know what kind of filter media you use in your filter except for the cartridges recommended to be used by that brand's filter line.
