I just got 2 dwarf gouramis for my 20 gallon tank. They began to swim around really fast after about 10 minutes and they're hitting the gravel and I'm worried they might hurt themselves. they're the only fish in it and I got my water tested at PetSmart right before and they said that the water parameters were all in a good range. The tank temperature is about 76°. Should I be worried?

How long has your tank been set up and is it fully cycled?

I hate to be the bearer of bad news, but you likely have 2 male dwarf gourami. If so, it usually doesn’t go well due to aggression between them.

In the pet store tank they seemed perfectly fine and it was a lot smaller with 3 of them

They typically do look fine in the pet store. Not so much when you get them home.

Is your tank fully cycled?

Yes the tank is fully cycled, is there a reason they're fine in the pet store that I could replicate in my tank

I can’t answer that, I just know from personal experience and a fair amount of reading that more than one male dwarf Gourami usually doesn’t end well. Especially in a 20 gallon tank.

Do you know exactly what your water parameters were when tested? I’d suggest you buy the API master test kit so you can test yourself. Until then, I’d also suggest partial water changes often. How often are you doing water changes?

I do about a 20% water change every week, and no I don't know any of the exact water parameters but they told me that the pH was a bit high but not high enough to harm any fish

I’d buy the API test kit tomorrow if I was you. I’d also do larger partial water changes.

Keep a very close eye on them and, if necessary, return one of them. That’s what I had to do.

P.S. You never did say how long your tank has been set up?

It's been set up for about 3 weeks and I used an established filter to cycle it

Sounds right, but I’m never convinced until I test myself.

So would water quality have to do with them fighting?

I’d say no. My water was pristine when I gave up on trying to keep 2. And that was in a 75 gallon tank with many hiding places.

And what did you add to keep the bacteria alive.

Fish in a displaytank will hardly ever show theit natural behaviour. Often the tanks are so crowded that "territorial" behaviour ism't possible. Also the lack.of.plants amd ornaments leave them "disorientated" not able to expose natural.behaviour.

Two DG's in one tank will mean war pretty soon.

Not a problem. Come back here if you can’t figure it out.

I used API bacteria starter along with the established filter, and I continue to use it with every water change, they seem to not care much about eachother anymore and don't chase eachother around although one of them seems to swim in little jerks sometimes like it's trying to shake something off

I think DoubleDutch is asking what your ammonia source was before you added fish to keep the beneficial bacteria alive.

I didn't have an ammonia source, I didn't realize that it was necessary

So you don’t know what the nitrogen cycle is (your profile says you do)?

I’ll go back to my original suggestion that you get a test kit and add that you should learn about the nitrogen cycle if you don’t already know how it works.
