Hello. My girlfriend has expressed a genuine interest in mollies. That being said, what can anyone tell me about caring for a group of say 3? At this point, tank might be 38 to some kind of 40. 1. Is 3 enough or too many in a group? 2. What gender ratio is acceptable? Or is all male or all female okay? 3. Determining gender? 4. What's a good temperature? 5. What are good tankmates? Other stocking may include Gourami (likely Pearl maybe Dwarf) Bolivian Rams Black Skirt Tetras Another Middle Schooler (maybe) Pleco (BN or Clown) (maybe) Snails Shrimp 6. Diet? 7. Behavioral problems to watch for? 8. Anything else? This is just a research phase. Thank you for your time.
