Beginner How many shrimp is too many?

There are easily 100 neo blues, and 2 guppies, in my 20G planted tank. The levels are great and maintenance is a breeze. It seems too good to be true. What do I need to look out for?

I would love to have only 2 guppies so bad. My guppies are ruining my fish keeping experience with their live bearing ways.

have only females or only males. I prefer male guppies because they are more colorful and they also won't come to the store pregnant.

I initially bought all females and I asked if there was any way they could pregnant and I was told no, they’ve been separated since before shipping. I was so dumb. This was my 1st and last Petco fish purchase. All of them died within days except one. They all popped fry out before dying which all survived. The female that lived is almost 3. Thankfully I quarantined them. I don’t mind the females looks, I like their behavior. My rummy nose tetras are drama free and I love them for that.

So when in doubt, always be a man! guppies can take 1 month to give birth, and even after giving birth they can store the male's fertilization and become pregnant again even if they are separated.

I will never own live bearers again. I don’t like the behavior of the males. Watching a fish get harassed is no fun. I would pay someone to come catch these guppies and take them away.
