Dwarf Gourami/opaline Gourami

[slady12]

I currently have a tank with some danios and cory catfish.
I was going to get a dwarf gourami, but many people have mentioned having illness issues with their gouramis.
I was at the pet store yesterday and noticed an opaline gourami (same as a three spot) and i was just wondering if anyone could either provide an opinion on having a dwarf gourami with health issues or if they know if my current fish will be alright with an opaline gourami

How big is the tank? I've kept Gouramis with Corys and Danios before so as long as your tank is big enough you should be ok. Just the one Opaline though? Not two or three? (I guess the size of your tank will determine this!)

36 gallons. And I would get however many gouramis i could.

Male Three Spot Gouramis can be terrors.  I would try to get maybe 3 females of similar size if you can.  I have a 36 gallon with a pair of Pearl Gouramis, a single female Opaline & a single female Paradise Fish.  They all live with (7) Glass Catfish, (6) Cherry Barbs & a single female Bristlenose Pleco.  I've had male Three Spot's and they can be very territorial in smaller tanks like 20 to 36 gallons.  If you had a 55 gallon or larger I'd say try a trio of one male & two females. 
 
EDIT:
 
Since Gold, Opaline, Blue, Lavender, etc. are all just color morphs of the Three Spot Gourami, you could mix & match to add some color to your tank.

I have two opaline, a male and female that hate each other and would most gladly kill the other if they had the opportunity. I had them in a 20g for a few months, the male would chase around the female and cause her to hide all the time, but really didn't do any damage. Then I got a 30g in Jan and put the male in there. I thought, well the female seems like she wants to breed and the male seems pretty lonely by himself, what could go wrong if I put them together in a larger tank? Nope. They tried killing each other for reals and I separated them again. They made a full recovery a few days later, but I don't think I'll be stupid enough to make that mistake again.
 
I've had the female in with shrimps (and baby shrimps) and she's never killed one. She was curious at first, but they were too fast for her. Though when I took her out of the tank the shrimps came out of hiding in the cave.
