yeah they seem promising. The tank look quite empty now though but i was told that i could keep about 12-15 dwarfs in this but he who sold me sad that about 25-30 is good with a good filitration and im turning around all the water about 10 times an hour but i'm not sure i can stock it with that many.

I laid a bit about how big they are, they are around 7cm the big ones and the smallest are around 4 cm of a possible 9 cm on both of the species
