At what age can male and females be put together in a tank?

+1 to Grif. You want to make sure the male CANNOT eat her. The earlier the better because the size difference is a major factor. If he cannot eat her (cannot get her in his mouth) you can put them together. Monitor them closely the first few days and keep them both well fed.

Pictures showing size comparison would be helpful as well.

Welcome and good luck.

Well I was told by the breeder they can live together, so I asked for another male so they would hopefully be the same size at some point or as near as.
BUT it is a female and the same age as the male, she is so small compared to him.
I did not know if there was a better time to try and to be honest I wondered just how big a prey my Goober could eat.

I know she is too small yet, she is at least 3 times smaller than the male. It just made me think if they could go together later or was it better
done when they were both very small.

yes, females grow way slower and same age males and females will have very big size difference. as well it is true, males and females can live together, but you can never relax if you have 2 or more frogs in one tank, you need to constantly monitor their behavior. I don't mean go all OCD about it, but just watch them.
i would say if your male is 6-7" and female 4-4.5" - that is ok for sure ( as sure as it can possibly be), 8+" male and 3" female - absolutely not ok.
even for similar size frogs make sure you have a big tank, so frogs will have possibility to get out of each other way, the more crowded it is the more aggression you'll see. actually same sex animals will fight if housed in small in comparison enclosures.

Think in this case; "can" live together does not means that it will be succesful for any length of time . If your male is 3 times the female size, there is a chance of the male trying to eat the smaller female. If female was around 2/3's of male size and they live in a large enclosure; your chance of success would increase. Good luck !

After reading the horror story of someone coming home and finding both dead I am so confused as to what to do now!
My first idea was that I wanted to house them together when I thought I had two males.
However when I found out one was female I thought hmmmmmmmmm ok this should be fine, but that story scared me

The breeder said he will happily exchange my female for a male, but I am not sure at all.

My idea is now to have Goobers tank next to a large water tank with Pickles tank the other side.
I will then cut two holes and make a tunnel into the middle tank.
The middle tank can have pond plants, the filter, rocks etc in it.
At the moment I have my tanks set up with their own water tanks inside the large ones.
I might do it like this...any thoughts please?
This may stop him from eating her
if they have their own space and large water area.

He is quite large nearly 6 inches and is only 5mths old, she is 5mths old but about 4 inches.
I shall wait to see how large she gets before trying this.

The breeder will gladly take your girl because they are harder to get than males. When I had my male African Bullfrog, was looking for a girl locally for a year and all local stores had what looked like males only.

I like your future set-up idea. If you use connecting tubes of different diameters (smaller on female side) that would only allow her to pass but not the larger male providing her with a resting side (if she figures all this up). I've seen something similar work when breeding large agressive fish like Central American cichlids, by using a divider with a hole that let's pass only the smaller female. The difference with frogs is that with their large mouths the male could grab the female in the middle section and it would be all over. Going back to the illustrated set-up; depending on water temperature you might consider a submersible heater for middle area.

If your frogs are 6 and 4 inches, agree with Lija that you can try and place them together now. Please make sure enclosure is large and observe them during initial contact to see what is their reaction to each other. Be ready to separate them again if the male intentions are nefarious, with these guys you never know. Good luck .

just noticed you're planning to place heat cables under the tanks, don't do that, place on a side.

I have then taped to the underside of the tanks with cardboard as insulation, I find if I keep the soil moist the heat spreads really well.
Even if they dig down to the plastic box floor they cannot burn themselves, they are also set on a thermostat.
Each night I dig a hole in the soil and test it then sit them in the hole...I call it tucking them in LOL

Just use styrofom to divide the cage into 2 sides. thats what i do sometimes as a quick fix to keep frogs from each other.it doseint really need to be very tall just a few inchs. i did tho rase a pair of pixies for over 2 years in the same cage durin that time thay wint from 10 gl tanks to as larg as 55 gal. and when i was moveing to my new house i hade them in a 5gal for weeks untill i was able to move them into there bigger cage the male was over 800 grams and the female was like 400 i rased them from the size of my thumb to huge animals and he never tryed to eat hur. BUT i will say it dose happn sometimes. right now ive got 16 pacman frogs and ive got them in 56QT bins 5 in each bin small,med,larg and i dont have any problems with them eating each other i do offer food every other day and thay are all will fed

Good idea about the size of tubes
I have a water heater, forgot to draw it in the picture lol
I have to have one here until spring comes as winter is very harsh even though indoors.
At the moment I have two flat 15wt water heaters for each frog...these are under a plastic guard in their trays.
I got a glass tube one and broke it!! So the new ones packed away before I had a chance to drop it or anything.

I will wait a month or two I think see if she grows a bit more (so scared now)
