3 Male Guppies,4 Pink Jewel Tetras, 2 Sparkling Gourami, 1 Oto, 2 Kuhli Loaches, 5 Cherry Shrimp, 2 Amano Shrimp, 1 Red Crystal Shrimp
Is this up to date, apart from planning to remove the guppies?
I don't think you should add another species of tetra, or any schooling fish - it'd be better to have one larger school of one species, ie the pink jewels. Having never heard of them, I've just looked them up and they get fairly chunky compared to your average neon, for example, so I'd say 8-10 of those would be good. (Edit: are these rosy tetras, does anyone know? They look similar.)
The one oto would appreciate company as they are shoaling fish - add at least another one if you can.
The kuhlis also like company, maybe add a third if you can.
Have you considered Endlers? They're similar to guppies but much smaller and when I had some they were far less hostile to each other. I had 6-8 males and while not strictly schooling fish, going off to do their own thing, they did look good as a group.
The oto is a survivor of the ich epidemic, his friends have been long gone. He's going to the LFS along with the guppies. Pink Jewel Tetras are a fairly recent tetra species, bred originally from some amazonian tetra. Its related to lemon tetras. Because they are a new species, they have a tendency to uh, die spontaneously
I had 6, then one died randomly being fine the night before. Two just died from popeye that turned out not be bacterial, so maybe hormonal. Put them in a QT and treated with Mardel Maracyn, and they just croaked as the final treatment day was coming
plus, their eyes never went down, so it mustve been something other than bacterial. I haven't found endlers at any LFS near me, so they're out. Pink Jewels are also known as White Tipped Rosy or Ornate Tetras i think...I would love to add more kuhlis, but its a "family tank" and "everyone has a say" and apparently some people find loaches "ugly"
i am trying though, i would love to get a male and female black kuhlis to go with my two.Do you only have one tank? I really want a larger tank too. I want cichlids (which I angrily(in my head) found out was pronounced sicklids. I was saying chicklids.) and oscars, but not a big enough tank. I do for some cichlids but I like my mix of fish.
I would have absolutely love to have some dwarf cichlids in my tank! As i was setting up my tank, i was dying for a pair of Triple Red Cockatoo Cichlids...but...then i found out they eat shrimp
And you can see i have a lot of shrimp 
Did you draw it or create it with a computer?
And i drew it on Microsoft paint...and i bet there are enough beautiful dwarf cichlids for your tank
