How do you sex a baby guppy?

Question

I got baby guppies, but they all look the same! How can you tell girl from boy.

Its really hard to see their fins. They are about 1mounth old, so the got no love organs yet, so I cant tell that way either. Please help.

Answer 1

The male is usually smaller and brighter in color than the female. Just remember that Guppies are sexually mature at 2 months old . They give birth to live young. Parents may chase young immediately after spawning so make sure you have plants where the babies can hide.

Answer 2

Livebearing fish (Guppies, Mollies, Platies, and so on.) breed internally, so the babies advance interior the secure practices of the female, for this reason why they are fairly elementary to reproduce. To acheive inner fertilization, the anal fin of the male has stepped forward between the fin rays right into a gonopoduim, that's particularly a penis, during which sperm flows into the female. In babies this turns into seen at approximately 3 weeks of age, and then they might desire to be separated, so as that they don't breed themselves. wish this replaced into effectual.

Answer 3

this is also how to tell guppy's,Molly's, Platte's and most other live bearing fish. this won't help on new borns you need to give them a six weeks but as soon as they mature a bit read below

the true to tell with out guessing about color ar size of tail is as follows.

under the guppy there is a fin called an anal fin(his sex organ) witch inserts sperm in to the femalee.it is long and is able to move left or right to insert into the femal fish

Answer 4

You are right that they lack the organs to tell them apart yet. You'll basically have to wait until they get a bit older and then you can sex them just like adults.
