Sugar coating and nicely nicely? I don't think so
My dwarf Gourami Vortigan passed away last month
He was perfectly fine in the morning and dead by the evening . I got home and he was floating with a large dark patch on his side ( It looked like some sort of internal bacterial problem that definitely wasn't there in the morning ). I tested the water immediately with my liquid kit, Ammonia was 0 Nitrite was 0 Nitrate was 15. I have no idea why or how he died that way as I do 25-40% water changes every week without fail, but I understand dwarf gouramis are prone to being generally weak ? He was such a lovely little chap, so friendly as well 
But it's been a month now, and I'm thinking of adding another centrepiece fish or small group
The tank is 12 gallons , running with a Fluval 3 ( since April and the filter was cycled for a month before that in the big tank ) and contains 10 pygmy cories ( which have been in there for about 3 months ) which are all still healthy and still in the tank, and also 1 apple snail . Since the Fluval is slightly overfiltering the tank , I wondered what I should have.
( The plants have been moved about but basically this is the tank )
I was pondering between these choices :
6 Male endlers OR
6 male guppies
Unless someone would like to suggest something else? ( not another dwarf gourami though please )
Even with the flow turned right down the current still pretty quick , which the cories seem to enjoy, but I suspect some surface dwellers like small hatchetfish may find that a bother and would probably be blasted about a bit.
I'm a bit unsure what to do really. I have looked at the stickied topic for 10 gallon tanks ( although I have an extra 2 gals to play with, not that it makes much difference ) and am still unsure.
Any reccomendations or advice?

It'll be nice to have a bit of colour in there .
