Dwarf Gourami in a Community Tank??
 
I have a 55 gallon Community tank with mollies and a platy. I am looking to introduce some new fish in the next couple of weeks. Will a Dwarf Gourami do well in the tank? If so, how many do I need I need?

A gourami would not be my choice to mix with livebearers. And the dwarf gourami carries some concerns anyway, check the profile for more on that. [Click the shaded name, it will link to our profile.]

In a 55g, some more suitable companions for livebearers would be some of the rainbowfish. Three species are in our propfiles, two of which are possibles: Dwarf Neon Rainbowfish and Boeseman Rainbowfish. Click names for those profiles with photos.

Other options are more livebearers, perhaps some swordtails (you have the space)?

Thank you, Byron. In my tank I have 3 balloon mollies, 2 dalmatian mollies, and a red wag platy. I am not sure that I like any of the above named fish.. I am looking for something with a little more color and a different body shape that the "goldfish body". Is it possible to maybe put tetras in? I am not worried about the babies from my livebearers (not really looking to keep any right now).

What are your tap water parameters, meaning here the GH (general hardness) and pH? And is the tank pH the same (or close)?

I had assumed before with livebearers that you probably had moderately hard water with a basic (above 7) pH, as would suit them, so I was thinking along those lines. Most tetra are the opposite, doing best in softer water, though there are some exceptions. When I know your GH and pH I can offer suggestions.

Here are the readings for my tap: pH 6.4, KH around 60, TH 120, NO2 & NO3-0, Ammonia is .25 and the readings for my tank this morning are pH 7.2, KH 60, TH 120, NO2 0, NO3 5, Ammonia 0. Yesterdays readings were a little different- pH- 6.8-7.0, KH -60, TH 120, NO2- .20, NO3 - 0-5, and ammonia is at .25

This is a bit tricky. Your water is soft (120 = 6-7 dGH), generally on the acidic side though if the tap is 6.4 I would wonder why the tank is rising to 7 and 7.2. Is there any calcareous gravel/sand in the substrate, or any shells, coral or calcareous rock?

To the fish, your molly are going to struggle in this soft and acidic water. Once we find what is raising the pH, if anything, and deal with that, you are well suited for soft water fish.

The only thing in my tank is a java fern, 12 or so small Anacharis plants, and Amazon Bronze colored Aquarium gravel.

Not knowing what that gravel is made of..don't suppose you still have the bag or any data? Or can you find it online so we can see the composition?

Another thought occurs to me, and that is your pH testing. These tests should always be done at approximately the same time of day because there is a diurnal pH fluctuation and taking the test in the early morning can give different results from early evening. Also, try to use daylight (not direct sunlight) to read the colour, because all artificial light has a different spectrum and the colours on the card and in the test vial may appear different under different light.

I am sorry it is Aztec Bronze here is the link to my gravels: Petco Aztec Bronze Aquarium Gravel at PETCO

Also, I test every morning around 8:00-8:30 in my kitchen near the sink under the window (so I don't spill fish water on my carpet LOL).

That gravel should be OK, it says it is inert.

So, back to the soft water and (probably) slightly acidic pH. You are wide open for many tetra. Have a look at our profiles, (tetras are in the characins section)many species with photos are included. The compatibility section mentions issues if any. You don't want to combine active with sedate fish, for instance. And a few of them can get a bit nasty.

I would do something about the mollies though; these are hard water fish that do not do well in soft water long-term.
