1) Angelfish, white clouds, or rams.
3) Aren't we all!!
4) Try Mesonauta Festivum if you're looking for a change.
Maybe aim for a Ram (any kind) with a type of hatchetfish (my marbled ones just spawned)!
Or even Mesonauta Festivum coupled with a Ram or Sterbai Corys
Keep us posted on what you choose!
