General Rule:
* 1-2 guppies per gallon: This is a good starting point for a healthy, happy guppy community.
So, for a 10-gallon tank, you could safely keep:
* 10-20 guppies: This assumes they're small guppies. If you're getting larger guppies, stick closer to the lower end of that range.
Important Considerations:
* Tank size: While 10 gallons is a decent size for guppies, it's important to remember that larger tanks are always better!
* Aquascaping: Lots of plants and hiding spots can help with overcrowding.
* Filtration: Make sure your filter is strong enough to handle the bioload from your guppy population.
* Water changes: Regular water changes are crucial, especially with a larger guppy community.
* Breeding: Guppies are prolific breeders! If you don't want a tank full of babies, consider getting all males or just a few females.
Overall, start with a smaller number of guppies and observe their behavior. If they seem cramped or stressed, it's time to re-evaluate your stocking levels.
