Not to mention the Three spot now has dominance in the tank, if you reintroduce the betta the gourami will give him everything he has until the betta is either dead or gone. The Three spot will also continue to attack the other fish. If you don't either get a larger tank or find more of your fish a new home you're going to run into alot more problems than aggression.
 
More than one gourami in a 10 gallon is BEGGING for trouble. Especially with something like a betta. If they aren't nipping each other now, they will be. I'd be surprised if my betta would have any fins left if I put him in a tank with my paradise fish for five minutes.

It's probably wise to stick to one gourami OR a betta in a 10, and stock community fish that can hold their own.
 
Considering the number of gouramis you are housing in your 20 gallon, you are in no place to preach to someone about keeping 1 gourami in a 10 gallon. Do the math.....need some help with it?...lol
 
Fish that are highly overstocked tend to just sit still in one place, they get more active as stocking levels come down. Look at the fish store's tanks with like 8 jack dempsey's in a 10 gallon tank. But we all know that at home, 1 of them is just too much for the tank and will kill whatever is in there with him.

Might be what happened.

There's a difference between really active and really stressed out, but you have to be experience to know the difference. Describe EXACTLY what the fish are doing. Sometimes stressed behaviour can seem like they're being active to the untrained eye.

The fish's adult size needs to be taken into consideration, using a 1" per gallon rule for fish like gouramis or any fish in general is not a good rule to use. I suggest rethinking your stocking levels and the species you keep in it.

except that he's having a problem with aggresion, i'm not.
 
I would suggest getting rid of the gourami because once he gets aggressive he wont stop until he either gets a bigger tank or hes in the tank alone.

Very good point! :)

There are numerous reasons why you can keep aggressive fish together safely if you overstock your aquarium.

- with a lot of fish present, there is too much destraction
- with a large population, instinctively the fish figures there is enough food in the area so it won't have to compete as aggressively
- I've read a theory that being in a large crowd will bring back a fish's 'fry' instincts.

...perhaps there are just SO many fish to defend a territory from, the fish realizes persistance is futile?

The pet store I worked for always kept large numbers of very aggressive fish together just so their aggression levels would lower. 'New comers' would be aggressive at first.....but there are so many fish to deal with, the aggressor would quickly simmer down :P

BTW...this doesn't always work. Sometimes you'll have a fish that will be aggressive regardless of present company.
