Guppy Breeding But Not Raising

Hi! I've decided to get 6 Cory catfish's, 4(one male three female) guppies, snails, and a still debated kind of shrimp for my 20 gallon tank. My question is, is allowing my guppies to breed as they please going to raise the bioload too much? I do not plan on humanly saving the fry, I intend to let nature do as it pleases, with help from the adult guppies, shrimp and Cory's. But I'm concerned letting them breed at all won't be healthy for the tank water

 

With that stocking I'd expect most fry to survive, so yes you will end up with an overstocked tank.

 

Dang... I was really hoping this selection would work out. I'll consider other options, but do you know if there's any other preditors I could put in the tank that Would handle all the fry? If I could make it work I'd like to

 

Most of the time the fish will stop eating the fry because there are so many. I would just get four male guppies.

 

That was my original idea but I'm very concerned about aggression, I've read it's hard to avoid when you just have males due to the fustration of not being able to breed. But I'll reconsider

 

I had 4 female guppies. That worked well. When you buy them they could be pregnant though.

A dwarf gourami might eat fry.

 

Most of my fry die, they get sucked into the filter, I usually just check the filter for them

They attempt to mate with everything, so frustration isn't the issue, its if one it slightly different from the others or much larger than the others then that one gets singled out for attempted mating.

 

Oooh well that's good to hear, idk if I like that as much as them being a hefty food source but it's still good to note

 

Maybe I will do just males if you think it'll be okay. At least a little aggression won't pollute the water

 

4 females was another idea, but I've read they just might change into males in that situation and if they pull that on me I'll definitely regret not getting a pretty male right from the start instead. The dwarf gourami is a cool idea

? Guppies can't change gender.

The only thing I can think of is baby guppies all have a triangular analfin like females, but by the time they are a couple of centimetres long you can tell the gender. They can't change gender thiugh.

 

I have 4 male guppies in my tank, no issues at all. They all get along just fine. If you don't want them to breed, just replace the male with another female or replace the females with males (which are prettier anyway).

Maybe I will go ahead and do 4 males. I love easy things. And it would be hard I feel to re-home surplus guppies if I messed up with breeding and ended up with more adults than I can handle

 

If you do all males I would recommend 6-8 of them to spread out any possible aggression. They can go a bit crazy without any females.

Do you think 6 Cory's and 6 guppies would be too much for a 20gal? Ill do that if it's not too much, I've got live plants helping me out

6 Cory’s and 6 guppies is fat from too much in my opinion especially with a planted tank

Well that's good news I'm starting to feel pretty comfy with this choice then

 

You have a 20 gal long? They should be fine with those numbers you could even get a few other things going too. If you don't have sand substrate already, I would change to it for the cories so they don't damage their barbels on gravel.

Sadly it's just a regular rectangle 20gal, but it's nice. I did already change to sand so that's a big check off the list lol. I think I'll slowly add the fish, cories first then guppies, both in two sets of three maybe with a few days in between and see how they all do. I don't like the looks if a too crowded tank so a snail and eventually some shrimp will about do it for me. If I was doing a male aand female guppy combo id consider a preditor for the fry but otherwise I'll keep it simple as possible at first. Thanks for the help! If there's anything else to keep in mind I'd love to hear it

Sounds like you should be ok. As long as it is cycled and ready to go.
