How many Small fish can I put in a 55gallon tank?
I might upgrade to a 55 gallon tank and wanted to know how many small fish I could put in the tank? I'm not going to get really any big fish, the biggest fish will either be a bristlenose Pleco (only grow to 3-4") or a redtail shark(can grow to 5"), all the other fish will be neon tetras, sunset platies, pristella tetras, 2 swordtails, and 4 mollies.... All I have to decide is how many of the smaller fish. I really like guppies, and want about 6 of them, so if anyone could tell me a general number of fish I could put in the 55 gallon tank... I know its not a small task, but I really want to know :-)

Doesnt have to be exact, and I know the rule of thumb but tons of aquarist on the forum have replied to other threads that its just a rule of thumb for begginers, but that it really depends on the bioload.

You might wanna reconsider having the swordtails and mollies mixed in with guppies. They sometimes don't get along too well. If you still wanna:

7-8 guppies
4 mollies
2 swordtails
1 redtail shark / brislenose pleco

I already have my mollies and swordtails and they get along great with my current guppies, my swordtail is very peaceful, my mollies r like in their own little world :-), these r the same fish im putting in the 55 gallon tank, I was just going to add a few fish because right now I have a 20 gallon tank . R u sure thats it?

You could probably add a few more guppies or 1 more molly or swordtail. They are decent sized fish, growing up to 5 inches (13cm).

And oh ok got ya. AS I said, sometimes they don't get along haha.

ha ha!! so I think of getting so many guppies, i think im just going to get 6 guppies and then 6 neon tetras, would that be good, i read somewhere on the forum that they have a very little bioload

you can have 55 inches of small fish. :)

haha, it would be funny to see like 35 ish guppies or neon tetras in a tank, pretty with either.

redtails get bigger than 5 inches dont they? Remember that guppies, mollys, and swordtails are livebearers. Keep the stocking down to accommodate for the fry.

I have about 40 fish in my 55gal tank including the redtail shark.
