Great news that your enjoying the tank!!!
I ran the above fish through aqadvisor for you using a tetra whisper 30 as your filter and guessed your tank dimensions at approx 24 x 16 x 12...works out at 20 gallons.
Then added 2 dwarf gouramis, 6 kuhli loaches and 6 flame tetra..... couldn't find the green bit... are they a bred colour anyone etc so about the same as hyphessobrycon flammeus???
If so, and this is just a guide, rates your tank at 66% full with no compatibility issues..... however this is a computer programme and I'd opt to listen to people here about issues than that, but is a good 'guide' to stocking options, just not 100% fool proof.
I have 2 male neon blue dwarf gouramis and love them, always on show, not scared of anything nowadays and always come to see me
in a smaller tank I'd say a male and female would be better so hopefully they will pair up
Also...mumphert!?! If he'd of found out about that he'd be sat in a corner sulking! With Mr Fish, he's a Boss! Haha
