Planning On Getting Honey Gouramis, Anything I Need To Know?

[KCB]

I've suffered a few losses this year. I had 6 Black Phantom Tetras but they've all succumbed to tumours now and the 3 Endler guppies I had dropped off one by one from some mysterious illness (water readings were fine but the fish went lethargic and died ), so I fancy a change in species. I'm really interested in getting a group of Honey gourami's however I don't know very much about the species. I've read the index page on this website and on another website but is there anything I should be aware of before I purchase them? Any illnesses they are likely to get? Will they be suitable for my tank? Here's some info on my current set up:
 
64 litres, long tank
Eheim filter with sponge media
Sand substrate, a piece of bog wood and fake plants (See picture)
Currently housing a small group of Pygmy Cories which I will probably add to
 
Essentially I just want another shoaling species of fish of reasonable size to fill the middle and upper levels that are also an attractive addition to the tank. If you have other species suggestions please let me know

Honies sometimes can be mistaken for Dwarf Sunset gourami at the LFS, which will succumb to dwarf gourami disease.
 
Females tend to have a grey line going down the length of their body and can look washed out of color, while males will have a dark area under their chest when they're mature (and feel like mating) and are very vibrantly orange. They're not really a shoaling species, but it's best to get 3:1 F/M ratio because males can get territorial (with each other) as they mature. It's possible that the LFS only has males, so be careful.
 
You would have been overstocked with just 6 of those tetras in a 64L. If you have cories too, you might want to limit yourself to just one or two of these gourami.

I didn't realise I was overstocked, I used this website (http/aqadvisor.com/) to calculate the stocking density and it said it was fine?
 
As for the Honey Gouramis, I saw a website recommend that they be kept in groups of 6 but if they're not meant to be a shoaling species I will probably give them a miss.
 
Thank you for the advice

Usually this site is my go-to source of information: http/www.seriouslyfish.com/species/trichogaster-chuna/
 
Though it says they do well in groups, you could still keep a pair. You'll become overstocked again if you get a group. It's like saying you need a group of bumble bee gudgeons to properly care for them when it's simply sadistic on the point of the viewer to keep them in a group just to be entertained by their fighting amongst themselves.
