Guppy Fry Growth

these guppies were born back in October they’re about 4 months now. I feel like these males have stopped growing and I want to know why and if I can do anything about it. The females of that group have grown more than these males.
This was my first batch of guppy fry ever . Since then I’ve had more and my biggest ones are almost as big if not bigger than these males.

 

I have heard that a female guppy’s first batch of fry is not usually the best and can be undersized. I had the same thing happen, and each generation is larger than the last

Your guppies look really cool!

 

Ah okay yeah I’m not sure if this was her first batch or not I bought her from PetSmart and was already pregnant.
And thank you I like to think they kind of look like Endler guppies

Yes! They do look just like Endlers! Being that they probably are part endler, there's a chance that they just won't get as large as non-endler male guppies. I have to say, though, that a couple of my endlers are well over a year old and they still are growing (very slowly, obviously!). In my experience the females have always grown faster and larger than the males.

 

Like mentioned above they appear to have endler genetics somewhere in their lineage which means they will probably not grow very large. Once a male guppy sexually matures they usually only grow for another few weeks before their growth is substantially slowed down. Their colors may continue to develop for several months and their fins may grow longer but their body has usually reached almost full size by this point. Females take longer to reach sexual maturity and grow for a longer time frame afterwards so the females of this batch may continue to grow for a little while but should be reaching close to full size if they haven't already.

 

Wow, they are so pretty
