Well there you go durbkat - opaline gouramies (a color morph of the three-spot gourami - trichogaster trichopterus) are one of the most aggressive (I consider them to be the most aggressive) gouramies commonly available at your average LFS. They also shouldn't ever be kept in pairs in a tank that small. You called one a 'he' but I don't know whether you new their sexes or are just assuming. regardless, 2 males in a 20 gallon are likely to fight to the death and the stress of the conflict usualy results in both of them dying anyway long before they actualy fight. If you had a male and female, the male typicaly chases the female until she dies and if you have two females, the larger will chase the smaller until she dies. Being highly territorial, they also don't like new additions to their tanks so the reaction to the tetras is perfectly normal in a tank that's only 20 gallons.
Any More Room?

Well I didn't know that you couldn't keep them in pairs simply because the lps didn't warn me about it. I thought they were peaceful like the blue gourami because I used to have one in a 10g with my 3 black tetras and my common pleco because I rescued the gourami when my friends tank sprung a leak and he put 2 blue gouramis, a male betta, and a black tetra in a big cup with no air stone or heater and that gourami was the only one to survive and it lasted a long time before it died for some reason.
I'm not blaming you for making that mistake as a lot of people do. However, I'm sure you know now that relying on any LFS for info. is a bad idea. It's lucky the blue gourami survived but I'm not that surprised as they are extremely hardy fish. BTW, blue gouramies are also three-spots (another color morph). The only reason it was peaceful would be because it was alone, probably female and had the boisterous black skirts as tankmates (they ignore plecs anyway for the most part). It also sounds like the gourami was added after the tetras so it would have not felt they were intruding on it's ground.
They're ramshorn snails, and a trumpet snail.
Not sure what the name of the shrimp was, but it was like 2 inches long I tihnk.
If you decide on the snails i'd go malaysian trumpet. They turn your substrate for you reducing the chance of anaerobic bacteria producing a pocket of poison that can kill your fish if left too long and then disturbed.

put your tank in here and see where your sitting on stocking levels. If you've got room i'd think the shrimp would be fine. gourami might eat him but probably not considering the shrimp is about as long as he is.

OK, got the shrimp today. It's called a bamboo shrimp. He helps clean out my filter intake tube that has plant on it. He eats it all up for me.
Now about the snails, what would be better to get, ramshorns or malaysian trumpet snails? Or does it now matter, just whatever I like better?

I'm not 100% certain but I would avoid the snails unless you want to be over-run. The danger of anaerobic pockets forming in your substrate is miniscule if you perform regular gravel vaccuums (except if you have a heavily planted tank of course) or have bottom-dwellers and particularly if your substrate's not too deep. All snails also produce ridiculous amounts of waste - though they also consume left-overs. I am only truly familiar with apple snails and these, I know, are not asexual and therefore do not multiply uncontrollably. Those you mentioned, I believe do. Also, as far as your stocking is concerned, you are fully stocked. Shrimp are ok to add because of how little waste they do produce but the snails are best avoided under the circumstances - particularly if that waste is going to multiply

Ok, thanks, that was very helpful. I guess I'll just skip on the snails then.
Thanks everyone for the help.
OK, I went to get some plants at Petco cause I had a gift card, and after I put them in and let everything settle for a bit, I see a snail crawling on the side of my tank! I'm not sure what kind he is, but can I keep him? If it reproduces asexual, and I see more, I can just get rid of them.
Would it be ok just to keep one.
