Input on multiple snakes in one tank.

[mrshawt]

It shouldn't be done. Think about this: You're significant other or a brother or sister of yours sharing your room with you. You get tired of that person regardless, you fight sometimes and all. That goes the same with any animal. That's just my input.

Apples to oranges.

So, let's take a new direction on this topic. The OP was asking about housing snakes together in general, but used his own enclosure as an example. His tank has males and females together. Also, they are all not the same size. One of them is becoming more aggressive. In this case, I would say that this situation could lead to further problems in the future. So, to the OP, I would consider finding a better housing option for all the snakes such as tubs or a rack.
