Most female guppies will come already pregnant and will overstock your 10 gallon within months. I suggest you have all males, you don't need to have females in the tank.
I’ve read somewhere that just male guppies can cause aggression? But the tank is nearly cycled it has a single female Betta. If they don’t cause aggression how many males should I get?SarahMcGee said:Actually I would suggest getting males because if you buy females they will probably already be pregnant and they store sperm so they will have babies every month for like 6 months and let me tell you that 10 gallon will be overcrowded before you can blink. The males may squabble a little but it shouldn't ever get very serious if you just stick with 5-6 in a 10 gallon. I wouldn't do less than 3 or one fish might constantly pick on another but you don't want them super crowded. I've kept like 20 young males in a 20 gallon for a few months and they didn't fight but it's really a matter of personality so you might get a "jerk" fish and have to rehome him.
Don't do 3 males and 2 females the males can literally chase the females to death if there are too many males to females. They just bother them until they die of stress.
Is this a new tank that hasn't been cycled? If it isn't cycled and you want to do a fish in cycle start with one guppy then slowly and more after it's been cycled.
Okay thanks.BalloonMollies said:If you want guppies I don't reccomend having them with your betta, they will pester the betta and she might tear them up real bad.
If the guppies are the only species in the tank, 5-6 male guppies would do well.
She doesn’t really roam around the tank much, she’s pretty chill. Thanks for the adviceRyanC14 said:
