What is the most number a guppy can give birth to?

Well, my guppy called Nmauva (pronounced, Nim - wava), had 54 babies, but we gave 6 away to my sister's best friend (neighbour) and we have 48 now.

So..

If guppies are beginners and haven't had babies before, they would give birth to around 10 - 60 maybe and well experienced mothers can give birth to 20 - 200 babies.

My guppy was a beginner and gave birth to 54.

Make sure you use a breeding net to have babies. Then take the mother guppy and put her in a separate bowl by herself to rest and with lots of rocks and maybe a small house for a few days (2 - 3 days). Then, put her with all the other fish.

Just don't take the babies out of the breeding net (you can buy breeding nets at your local fish store), because then the female fish or male fish can eat the babies. The mother and father can also eat their own babies.

Please follow all this information and I hope I gave you enough information.
