corns together or not?

i have 4 baby cornsnakes comming to me. a male and female flouresent cornsnakes and a male and a female hypomelonistis cornsnakes. can they all be housed together? what size tank is best for them? and can they be kept together as adults or should they be seperated? also if they are all together in a tank should feeding be done seperate in another tank? i'm new to this and any info is appreciated thanks.......

housing together

In the end it all comes down to personal choice, but there are numerous reasons not to house corns together. Some of these reasons include
1) Cannabalism (rare, but it happens)
2) Transmission of parasites/disease
3) Inability to tell which one pood/regurged/etc.
4) Stress (can cause nonfeeding and failure to thrive)
5) Early breeding it's complictations - after just a few months old, the pairs should be seperated until the female is breeding size to prevent early breeding.

If you do decide to house them together (which I don't recommend) it is a must to feed in seperate containers. Corns have eaten each other when fed in the same container. 2 snakes grab the opposite ends of the mouse, and just keep on swallowing when they reach the other snake.

I feed all my corns in a seperate container anyways, to prevent ingestion of substrate.

A 20 gallon long or larger tank is fine for one adult corn - hatchlings can be housed in adult-sized tanks without problems if there are enough hide spots. Since the snakes are hatchlings, they can be kept in small shoebox plastic containers for a while...larger ones would work as permanent enclosures.

Just to give another point of view...
I house my snakes together and have had no problems. You have to be willing and able to be super careful when housing together though. You MUST feed in seperated containers. I also feed mine on separate days so I know who is pooing, regurging etc. Alot of posts have been done on this topic so look up them too to see everyones point of view. If these are your first snakes then go out and get a cornsnake manual which can answer most of the small niggling worries you might have. They also guide you through the feeding, health, breeding, colours, etc etc questions you will no doubt have sooner or later.

In my personal experience I have five vivs, three with pairs of cornsnakes in and two with a single cornsnake. My pairs of corns live together without stress and seem happy, one of my single corns is a very techy snake and doesn't like any other snake in with him, and my last single snake is a baby corn and soon will be moving into a newly built viv with another baby corn and will share all being well.

I find that two males do not live together happily, but a male and female seem fine.

I do agree with the parasite and disease thing, if you have only one snake per viv you do not risk infection to other snakes.

I also agree about feeding the cornsnakes in seperate places because one of my snakes tried eating the others mouse, and ended up with her head in his mouth, and the only way to seperate them in this instance was under a cold water tap ( which I will never do again because I realised afterwards the shock could have killed both of them).

Pinatamonkey took the words right out of my mouth.

I definitely think you should not mix sexes.

It also can cause stress and your corns wont come out to play as much.

If you do make tonnes and tonnes of hide and separate play things, like 2 branches and such.
